Heidelberg Castle (in German: Heidelberger Schloss) is a famous ruin in Germany and landmark of Heidelberg. The castle ruins are among the most important Renaissance structures north of the Alps.
The castle has only been partially rebuilt since its demolition in the 17th and 18th centuries. It is located Template:Convert up the northern part of the Königstuhl hillside, and thereby dominates the view of the old downtown. It is served by an intermediate station on the Heidelberger Bergbahn funicular railway that runs from Heidelberg's Kornmarkt to the summit of the Königstuhl.
The earliest castle structure was built before 1214 and later expanded into two castles circa 1294; however, in 1537, a lightning-bolt destroyed the upper castle. The present structures had been expanded by 1650, before damage by later wars and fires. In 1764, another lightning-bolt caused a fire which destroyed some rebuilt sections.

thumb's Kalendarium Hebraicum published in 1527 (detail).]] Heidelberg was first mentioned in 1196 as "Heidelberch". In 1155 Conrad of Hohenstaufen was made the Count Palatine by his half-brother Frederick Barbarossa, and the region became known as the Electorate of the Palatinate. The claim that Conrad's main residence was on the Schlossberg (Castle Hill), known as the Jettenbühl, cannot be substantiated. The name "Jettenbühl" comes from the soothsayer Jetta, who was said to have lived there. She is also associated with Wolfsbrunnen (Wolf's Spring) and the Heidenloch (Heathens' Well). The first mention of a castle in Heidelberg (Latin: "castrum in Heidelberg cum burgo ipsius castri") is in 1214, when Louis I, Duke of Bavaria of the House of Wittelsbach received it from Hohenstaufen Emperor Friedrich II. The last mention of a single castle is in 1294. In another document from 1303, two castles are mentioned for the first time:
- The upper castle on Kleiner Gaisberg Mountain in Berlin, near today's Hotel Molkenkur (destroyed in 1537);
- The lower castle on the Jettenbühl (the present castle site).
All that is known about the founding of the lower castle is that it took place sometime between 1294 and 1303. The oldest documented references to Heidelberg Castle are found the 1600s:
- The Thesaurus Pictuarum of the Palatinate church counsel Markus zum Lamb (1559 to 1606);
- The "Annales Academici Heidelbergenses" by the Heidelberg librarian and professor Pithopoeus (started in 1587);
- The "Originum Palatinarum Commentarius" by Marquard Freher (1599);
- The "Teutsche Reyssebuch" by Martin Zeiller (Strasbourg 1632, reprinted in 1674 as the "Itinerarium Germaniae").
All of these works are for the most part superficial and do not contain much information. In 1615, Merian's Topographia Palatinatus Rheni described Prince Elector Ludwig V as he "started building a new castle one hundred and more years ago". Most of the descriptions of the castle up until the 18th century are based on Merian's information. Under Ruprecht I, the court chapel was erected on the Jettenbühl.
Palace of kings, prison of popesTemplate:Anchor
When Rupert III of Germany became the King (Emperor) of Germany in 1401, the castle was so small that on his return from his coronation, he had to camp out in the Augustinians' monastery, on the site of today's University Square. What he desired was more space for his entourage and court and to impress his guests, but also additional defences to turn the castle into a fortress.
After Ruprecht's death in 1410, his land was divided between his four sons. The Palatinate, the heart of his territories, was given to the eldest son, Ludwig III. Ludwig was the representative of the emperor and the supreme judge, and it was in this capacity that he, after the Council of Constance in 1415 and at the behest of Emperor Sigismund, held the deposed Antipope John XXIII in custody before he was taken to Burg Eichelsheim (today Mannheim-Lindenhof).
On a visit to Heidelberg in 1838, the French author Victor Hugo took particular pleasure in strolling among the ruins of the castle. He summarised its history in this letter:

Reformation and the Thirty Years WarTemplate:Anchor
It was during the reign of Louis V, Elector Palatine (1508–1544) that Martin Luther came to Heidelberg to defend one of his theses (Heidelberg Disputation) and paid a visit to the castle. He was shown around by Louis's brother, Wolfgang, Count Palatine, and in a letter to his friend George Spalatin praises the castle's beauty and its defenses.
In 1619, Protestants rebelling against the Holy Roman Empire offered the crown of Bohemia to Frederick V, Elector Palatine who accepted despite misgivings and in doing so triggered the outbreak of the Thirty Years War. It was during the Thirty Years War that arms were raised against the castle for the first time. This period marks the end of the castle's construction; the centuries to follow brought with them destruction and rebuilding.
After his loss at the Battle of White Mountain on 8 November 1620, Frederick V was on the run as an outlaw and had to release his troops prematurely, leaving the Palatinate undefended against General Tilly, the supreme commander of the Imperial and Holy Roman Empire's troops. On 26 August 1622, Tilly commenced his attack on Heidelberg, taking the town on 16 September, and the castle few days later.
When the Swedes captured Heidelberg on 5 May 1633 and opened fire on the castle from the Königstuhl hill behind it, Tilly handed over the castle. The following year, the emperor's troops tried to recapture the castle, but it was not until July 1635 that they succeeded. It remained in their possession until the Peace of Westphalia ending the Thirty Years War was signed. The new ruler, Charles Louis (Karl Ludwig) and his family did not move into the ruined castle until 7 October 1649.
Victor Hugo summarized these and the following events:
Nine Years' WarTemplate:Anchor
thumb After the death of Charles II, Elector Palatine, the last in line of the House of Palatinate-Simmern, Louis XIV of France demanded the surrender of the allodial title in favor of the Duchess of Orléans, Elizabeth Charlotte, Princess Palatine who he claimed was the rightful heir to the Simmern lands. On 29 September 1688, the French troops marched into the Palatinate of the Rhine and on 24 October moved into Heidelberg, which had been deserted by Philipp Wilhelm, the new Elector Palatine from the line of Palatinate-Neuburg. At war against the allied European powers, France's war council decided to destroy all fortifications and to lay waste to the Palatinate (Brûlez le Palatinat!), in order to prevent an enemy attack from this area. As the French withdrew from the castle on 2 March 1689, they set fire to it and blew the front off the Fat Tower. Portions of the town were also burned, but the mercy of a French general, René de Froulay de Tessé, who told the townspeople to set small fires in their homes to create smoke and the illusion of burning prevented wider destruction.
Immediately upon his accession in 1690, Johann Wilhelm, Elector Palatine had the walls and towers rebuilt. When the French again reached the gates of Heidelberg in 1691 and 1692, the town's defenses were so good that they did not gain entry. On 18 May 1693 the French were yet again at the town's gates and took it on 22 May. However, they did not attain control of the castle and destroyed the town in attempt to weaken the castle's main support base. The castle's occupants capitulated the next day. Now the French took the opportunity to finish off the work started in 1689, after their hurried exit from the town. The towers and walls, that had survived the last wave of destruction, were blown up with mines.
Removal of the court to MannheimTemplate:Anchor
thumb served two congregations (Protestant and Catholic) for a time and was the reason why the court removed to Mannheim.]]
In 1697 the Treaty of Ryswick was signed, marking the end of the War of the Grand Alliance and finally bringing peace to the town. Plans were made to pull down the castle and to reuse parts of it for a new palace in the valley. When difficulties with this plan became apparent, the castle was patched up. At the same time, Charles III Philip, Elector Palatine played with the idea of completely redesigning the castle, but shelved the project due to lack of funds. He did, however, install his favorite court jester, Perkeo of Heidelberg to famously watch over the castle's wine stock. Perkeo later became the unofficial mascot of the city. In 1720, he came into conflict with the town's Protestants as a result of fully handing over the Church of the Holy Spirit to the Catholics (it had previously been split by a partition and used by both congregations), the Catholic prince-elector moved his court to Mannheim and lost all interest in the castle. When on 12 April 1720, Charles announced the removal of the court and all its administrative bodies to Mannheim, he wished that "Grass may grow on her streets".
The religious conflict was probably only one reason for the move to Mannheim. In addition, converting the old-fashioned hill-top castle into a Baroque palace would have been difficult and costly. By moving down into the plain, the prince-elector was able to construct a new palace, Mannheim Palace, that met his every wish.
Karl Phillip's successor Karl Theodor planned to move his court back to Heidelberg Castle. However, on 24 June 1764, lightning struck the Saalbau (court building) twice in a row, again setting the castle on fire, which he regarded as a sign from heaven and changed his plans. Victor Hugo, who had come to love the ruins of the castle, also saw it as a divine signal:
In the following decades, basic repairs were made, but Heidelberg Castle remained essentially a ruin.
Slow decay and Romantic enthusiasmTemplate:Anchor
In 1777, Karl Theodor became ruler of Bavaria in addition to the Palatinate and removed his court from Mannheim to Munich. Heidelberg Castle receded even further from his thoughts and the rooms which had still had roofs were taken over by craftsmen. Even as early as 1767, the south wall was quarried for stone to build Schwetzingen Castle. In 1784, the vaults in the Ottoheinrich wing were filled in, and the castle used as a source of building materials.
As a result of the German mediatisation of 1803, Heidelberg and Mannheim became part of Baden. Charles Frederick, Grand Duke of Baden welcomed the addition to his territory, although he regarded Heidelberg Castle as an unwanted addition. The structure was decaying and the townsfolk were helping themselves to stone, wood, and iron from the castle to build their own houses. The statuary and ornaments were also fair game. August von Kotzebue expressed his indignation in 1803 at the government of Baden's intention to pull down the ruins. At the beginning of the nineteenth century, the ruined castle had become a symbol for the patriotic movement against Napoleon.
Even before 1800, artists had come to see the river, the hills and the ruins of the castle as an ideal ensemble. The best depictions are those of England's J. M. W. Turner, who stayed in Heidelberg several times between 1817 and 1844, and painted Heidelberg and the castle many times. He and his fellow Romantic painters were not interested in faithful portrayals of the building and gave artistic licence free rein. For example, Turner's paintings of the castle show it perched far higher up on the hill than it actually is.
The saviour of the castle was the French count Charles de Graimberg. He fought the government of Baden, which viewed the castle as an "old ruin with a multitude of tasteless, crumbling ornaments", for the preservation of the building. Until 1822, he served as a voluntary castle warden, and lived for a while in the Glass Wing (Gläserner Saalbau), where he could keep an eye on the courtyard. Long before the origin of historic preservation in Germany, he was the first person to take an interest in the conservation and documentation of the castle, which may never have occurred to any of the Romantics. Graimberg asked Thomas A. Leger to prepare the first castle guide. With his pictures of the castle, of which many copies were produced, Graimberg promoted the castle ruins and drew many tourists to the town.
Planning and restorationTemplate:Anchor
thumb The question of whether the castle should be completely restored was discussed for a long time. In 1868, the poet Wolfgang Müller von Königswinter argued for a complete reconstruction, leading to a strong backlash in public meetings and in the press.
In 1883, the Grand Duchy of Baden established a "Castle field office", supervised by building director Josef Durm in Karlsruhe, district building supervisor Julius Koch and architect Fritz Seitz. The office made a detailed plan for preserving or repairing the main building. They completed their work in 1890, which led a commission of specialists from across Germany to decide that while a complete or partial rebuilding of the castle was not possible, it was possible to preserve it in its current condition. Only the Friedrich Building, whose interiors were fire damaged, but not ruined, would be restored. This reconstruction was done from 1897 to 1900 by Karl Schäfer at the enormous cost of 520,000 Marks.
Castle ruins and tourism
The oldest description of Heidelberg from 1465 mentions that the city is "frequented by strangers", but it did not really become a tourist attraction until the beginning of the 19th century. Count Graimberg made the castle a pervasive subject for pictures which became forerunners of the postcard. At the same time, the castle was also found on souvenir cups. Tourism received a big boost when Heidelberg was connected to the railway network in 1840.
Mark Twain, the American author, described the Heidelberg Castle in his 1880 travel book A Tramp Abroad: Template:Cquote
In the 20th century, Americans spread Heidelberg's reputation outside Europe. Thus, Japanese also often visit the Heidelberg Castle during their trips to Europe. Heidelberg has, at the beginning of the 21st century, more than three million visitors a year and about 1,000,000 overnight stays. Most of the foreign visitors come either from the USA or Japan. The most important attraction, according to surveys by the Geographical Institute of the University of Heidelberg, is the castle with its observation terraces.
Reflections on the "Heidelberg Mythos"
The Heidelberg professor Ludwig Giesz wrote, in his 1960 essay titled "Phenomenology of the Kitsches", about the meaning of the ruins for tourism:
Professor Ludwig Giesz goes further in his remarks about the ruins:
Also Günter Heinemann raises the question of whether one could restore the Heidelberg Castle incompletely. Near the view from the Stück-garden over the deer moat (Hirschgraben) of the well-kept ruins of the castle interior, he asks himself whether one should not redevelop the whole area again.

The "Winter King" Frederick V
thumb: The "Winter King"]]
Frederick V, Elector Palatine married the English king's daughter Elizabeth Stuart. The marriage involved great expense. Expensive festivities were organized and for them; he commissioned the Elizabeth gate at the piece garden be built.
From October 1612 until April 1613, Frederick V spent nearly a half year in England, and though only 17 years-old, thereby took up contact with important architects, who later undertook changes and new building plans for the Heidelberg Castle. Inigo Jones and Salomon de Caus, who knew each other well, stood in the service of the English king's court. Caus accompanied the newlyweds on their return journey to Heidelberg. Jones came to Heidelberg as well in June 1613. Very soon, the building of an enormous garden was tackled. However, the plants were intended for level ground, and the slope of the mountain had to be converted. First earth movements had to be achieved, which contemporaries regarded as the eighth wonder of the world.
Under the rule of Frederick V, the Palatine sought Protestant supremacy in the Holy Roman Empire, which however ended in a debacle. After 1619, Frederick V - against the expressed advice of many councellors -was chosen as the Bohemian king, he could not maintain the crown after he lost at the Battle of White Mountain (Bílá hora) (height 379m/1243 ft) against the troops of the Emperor and the Catholic League. He received the mocking name "Winter King" since his kingdom had lasted only somewhat more than one winter. With the Thirty Years War, Frederick V entered another phase and became a political refugee.
As Frederick V left Heidelberg, it is said that his mother, Louise Juliana of Nassau proclaimed: "Oh, the Palatine is moving to Bohemia." After his escape to Rhenen in Holland, Emperor Ferdinand II in 1621 put the imperial ban on Friedrich (Prince Electors). The Rhein Palatinate was transferred in 1623 to Duke Maximilian I of Bavaria, who also bought the Upper Palatinate from the emperor.
In Rhenen, to the west of Arnheim, the family lived on saved public funds and the generous support of the English king, initially also of the Netherlands, united by the support of the government. For the remainder of his life, Frederick hoped to win back his position in the Palatinate, but he died in exile in 1632.
Elizabeth Charlotte, Princess Palatine
thumb]] Elizabeth Charlotte, Princess Palatine was the duchess of Orléans and the sister-in-law of Louis XIV of France. When the Palatinate-Simmern branch of the Wittelbachs died out, Louis XIV laid claim to the Palatinate and started the War of the Grand Alliance, which laid waste to the Palatine. Liselotte, as she is affectionately known, was forced to look on helplessly as her country was ravaged in her name.
Liselotte, granddaughter of Frederick V, was born in Heidelberg Castle and grew up at her aunt Sophia of Hanover's court in Hanover. She often returned to Heidelberg with her father. At the age of 19, she was wedded for political reasons to the brother of the king of France. It was not a happy marriage. When her brother Charles died without issue, Louis XIV claimed the Palatinate for himself and declared war on her.
Liselotte wrote in a letter to her aunt Sophia in Hanover:
- "So I judge that papa must not have understood the magnitude of the matter of signing me over; but I was a burden to him and he was worried that I would become an old maid, so got rid of me as quickly as he was able. That was to be my fate."
Even after thirty-six years in France, she still thought of Heidelberg as her home, and wrote in a letter to Marie Luise von Degenfeld:
- "Why does the prince elector not have the castle rebuilt? It would certainly be worth it."
The House of Orléans is descended from the children of Liselotte and Philipp, which came to the French throne in 1830 in the person of Louis-Philippe of France.
Liselotte is estimated to have written 60,000 letters, around one-tenth of which, survive to this day. The letters are penned in French and German and describe very vividly life at the French court. Most of them she wrote to her aunt Sophia and her half-sister Marie-Luise, but she also corresponded with Gottfried Leibniz.
Liselotte's upbringing was rather bourgeois. Charles I Louis, Elector Palatine loved to play with his children in the town of Heidelberg and to go for walks along the slopes of the hills of the Odenwald. Liselotte, who later described herself as a "lunatic bee" (German: "dolle Hummel"), rode her horse at a gallop over the hills round Heidelberg and enjoyed her freedom. She often slipped out of the castle early in the morning to climb a cherry tree and gorge herself with cherries. In 1717, looking back on her childhood in Heidelberg, she wrote:
Charles de Graimberg
The French Kupferstecher (copperplate engraver) Count Charles de Graimberg fled the French Revolution and emigrated with his family to England. He applied in 1810 to Karlsruhe, in order to begin training with the Hofkupferstecher of Baden, Christian Haldenwang, who was a friend and neighbour of Graimberg's brother Louis. After Graimberg went to Heidelberg to sketch the Castle for a landscape, he stayed for the remaining 54 years of his life. With his copper passes of the Castle ruins, he documented its condition and put the foundation-stone for the Roman Castle, which should protect the ruin against final decay.
In his house (today: Palace Graimberg, at the beginning of the footpath to the Castle) he developed a curiosity cabinet with pieces of find from the Castle, which later became the basic pieces of the Kurpfälzisches Museum. He, by the way, financed his collection "of the Altertümer" for the history of the city and the Castle, from his own fortune. It is due to him that the Castle still stands. He accomplished also the first historical excavations in the Castle and lived a time long in the Castle yard, in order to prevent that the citizens of Heidelberg take building material for their houses from the Castle out-fallow.
In order Graimberg's wrote Thomas A. Leger's the first sources written on the basis written Castle leader. A copy of this leader from that 1836 "Le guide voyageurs dans la ruin de Heidelberg " ("Leader for foreigner by the ruins of the Heidelberger of lock"), was acquired by Victor Hugo during his stay in Heidelberg. This copy provided with notes is issued today in "the Maison de Victor Hugo" in Paris.
Of Charles de Graimberg reminds an honour board, which was attached 1868 at the passage to the Altan: "The memory of Karl count von Graimberg, born to Castle pair in France 1774, died to Heidelberg 1864. Heidelberg castle is home to the second largest beer keg in the world!"
The forecourt is the area enclosed between the main gate, the upper prince's well, the Elisabeth gate, the castle gate and the entrance to the garden. Around 1800 it was used by the overseer for drying laundry. Later on it was used for grazing cattle, and chickens and geese were kept here.
The approach to the forecourt takes you across a stone bridge, over a partially filled-in ditch. The main gate was built in 1528. The original watchhouse was destroyed in the War of the Grand Alliance and replaced in 1718 by a round-arched entrance gate. The gate to the left of the main entrance was closed by means of a drawbridge.
Goethe memorial tabletTemplate:Anchor
In 1961 a stone tablet was erected on a ruined wall of the aviary to replace an older tablet. The inscription on the tablet includes verses by Marianne von Willemer reflecting on her last meeting with Johann Wolfgang Goethe written on 28 August 1824, on the occasion of Goethe's 75th birthday.
- "On the terrace a high vaulted arch
- was once your coming and going
- the code pulled from the beloved hand
- I found her not, she is no longer to be seen"
- This poem written by Marianne von Willemer
- in remembrance of her last meeting with
- Goethe in the Fall of the year 1815
Directly across from the Goethe memorial tablet, stands the Ginkgo tree, from which Goethe gave a leaf to Marianne von Willemer as a symbol of friendship. The poem was published later as "Suleika" in West-östlicher Diwan.
The text of the poem begins:
- Ginkgo Biloba
- This leaf from a tree in the East,
- Has been given to my garden.
- It reveals a certain secret,
- Which pleases me and thoughtful people.
- ...Template:Spaces–Johann Wolfgang Goethe
The letter containing this poem with which Goethe included two Ginkgo leaves can be viewed in the Goethe Museum in Düsseldorf. The Ginkgo, planted in 1795, that Goethe lead Marianne von Willemer to in September 1815, is no longer standing today. Since 1928 the Ginkgo tree in the castle garden was labelled that it was "the same tree that inspired Goethe to create his fine poem". The tree was probably still standing in 1936.
The former harness room, originally a coach house, was in reality begun as a fortification. After the Thirty Years War it was used as a stables as well as a toolshed, garage and carriage house.
Upper Prince's Fountain
thumb The Upper Prince's Fountain was designed and built during the reign of Prince Karl Philipp. Over the gate to the fountain house is his monogram with the date 1738 chiseled in the stone. On the right side of the stairway to the fountain is the following inscription:
- [DlreCtione] ALeXanDro Blblena CVra et opera HenrICl Neeb Fons hIC PrInCIpaLIs reparat(Vs) PVrIor sCatVrlt
- (Translation: This work was undertaken under the oversight of Alessandro Galli da Bibiena and Heinrich Neeb.)
The inscription a chronogram for the date 1741. Through this fountain and the Lower Prince's Fountain were the water needs of the Prince's residences in Mannheim met until into the 19th century.
In 1798, Johann Andreas von Traitteur recalled this water transport: Template:Cquote Quote from Hans Weckesser:"Beloved Water Tower. The History of Mannheim's landmarks"
The water quality in Mannheim was so bad, that upper-class families of the court financed this transport of water from Heidelberg to Mannheim. In the princely residence, until 1777 there was a court position titled "Heidelberg Water-filler".
