Deutz was established under Roman Emperor Constantine I in 310 AD, when he established »Castrum Divitia«, a military camp, built in on the opposite river bank of Colonia Claudia Ara Agrippinensium. Camp and city were linked via a bridge from the same time. During the Middle Ages, Deutz was an important centre of learning in medieval Germany. Up into the early Middle Ages it was known by the Latin name Divitia, from the 10th century as Tuitium. It was located on the right bank of the Rhine, opposite Cologne, which grew up on the left bank. The important abbey was home to many influential theologians, such as Rupert of Deutz.
Deutz was formally incorporated into Cologne in 1888. Modern Deutz is the part of the Cologne city centre on the right bank of the river.
