Acht Ecken (Eight Corners) is the name of a former architectural ensemble in Potsdam, Germany.
At the intersection of Schwertfegerstraße and Friedrich-Ebert-Straße, four identical baroque houses were built on the corner plots in 1771 by Bayreuth architect Carl von Gontard. Each building was designed with a concave facade towards the crossroads, resulting in eight corners in total.
Today, only one of the four buildings is left. Friedrich-Ebert-Straße was turned into a wide traffic artery after WWII destructions, occupying the two eastern building sites. The southwestern property was rebuilt with a modern prefab concrete building in the 1960s.
