Auermühle

Auermühle is an industrial building complex in Graurheindorf along the Rhine with two prominent silos and storage structures that once processed grain. The structures retain their distinctive mill architecture with tall towers and multiple storage buildings arranged along the waterfront.

The complex was built as a wheat mill in 1923 by the Cremer family and acquired in 1926 by Dr. Carl Auer, who established the Bonner Weizenmühle Carl Auer. After operating as a grain facility for decades, it was converted into modern office space and has housed major Siemens operations since 2011.

The transformation from an industrial grain mill to modern office spaces reflects the shift in Bonn's economic focus following its status change as capital.

The site sits directly along the Rhine in the port area and is easily accessible from central Bonn. The grounds are open to view from public areas, making it ideal for exterior observation and architectural photography of the main structures.

One of the two silos is still called 'Kornkirche' due to its distinctive church-like shape, a nickname that reflects its unusual silhouette. After conversion to offices, this silo retained only two of its original storage tubes, visibly altering its original structure.
