When the building collapsed more than 10 years ago, it presented the historians with an unprecedented task. Every single leaf had to be cleaned and returned to its order. Only then was it possible to use them again. Some of the photos and plans suffered severe damage and are still being painstakingly restored.
In 2021, the modern new building on the Eifelwall was opened and its rooms offer a pleasant atmosphere for exploring the old treasures and documents. It is a source of information for researchers, but all citizens* who are interested in Cologne's history are also welcome.
