The foundations of a Roman building that is probably the oldest library in Germany have been uncovered in central Cologne in archaeological excavations during the construction of a new parish building for the protestant church.

The walls are comparable to other libraries of the Roman Empire, such as the one in Ephesus, says Dirk Schmitz, the head of the Cologne archaeological monument authority. It dates back to between 150 and 200 A.D. and, as was usually the case in Roman cities, is located in the ancient forum.

“There are niches along the inside of the walls which have remained intact,” Schmitz says. “They were almost certainly used to store the scrolls.” A small annex to the building was probably an alcove where a statue of the Roman goddess Minerva once stood, he says.
