Main Post Office

The project was initiated by Postmaster General Heinrich von Stephan, with the remaining foundations of the old Dominican monastery serving as its base. Planning was handled by the Technical Building Department of the Reich Postal Office in Berlin under August Kind, while architect Karl Doflein designed the façade. The building was inaugurated on 15 November 1893 in the presence of senior postal officials. An extension later followed to house Cologne's postal giro office, and the regional postal directorate eventually relocated to Clever Straße/Wörthstraße in Neustadt-Nord.

The building combined Cologne's main post office, telegraph office and regional postal directorate under one roof. When the Deutsche Bundespost was privatized in the postal reform, the directorate's responsibilities were distributed among the newly created postal service divisions.

Already in the 1920s, structural damage forced a simplified renewal of the original façade. Severe wartime destruction in 1943 led to a thorough reconstruction, giving the building a plainer ashlar façade.

The structure was demolished in 1997–1998 to make way for a new senior residence. Since its original fabric had already been substantially altered, heritage authorities raised no objections.
