St. Marien am Behnitz is the second-oldest Catholic church in the area of Berlin, Germany, after St. Hedwig's Cathedral.

Beginning in 1825, plans for a church were under way when the congregation grew with many soldiers from different parts of Prussia moving to the Spandau garrison.

[2] In 1847 the foundation was laid for a new church within the city walls at the Behnitz, one of the oldest settlements of Spandau.

[2] August Soller was responsible for the application and refused his approval, offering to deliver his own plans, which were more in keeping with the new royal program for church buildings.

The diocese sold the building in 2002 to a private investor who planned to use it for concerts and literary events, under the condition that liturgical use would still be possible, and the requests of preservation of a historic monument fulfilled.
