The Former Prussian Government Building in Koblenz is a significant architectural structure located at the Deutsches Eck, where the Rhine and Moselle rivers converge. Constructed between 1902 and 1906, the structure was designed by Berlin architect Paul Kieschke in the Wilhelmine Neo-Renaissance style.

Constructed of sandstone, the building features a symmetrical facade with a central projecting risalit. This central section displays a segmented-arch pediment supported by Ionic pilasters. The overall composition follows a tripartite division with a rusticated ground floor, a piano nobile distinguished by Corinthian columns, and a substantial cornice. The architectural design includes a mansard roof with dormer windows and a monumental staircase.

The building originally functioned as the administrative headquarters for the Prussian Rhine Province. Its strategic placement at this historically significant river junction represented the extension of Prussian administrative authority into the Rhineland region. The building's layout is organized in an E-shaped formation around a central courtyard.

During World War II, the structure sustained substantial damage from aerial bombardment in 1944. Reconstruction occurred between 1948 and 1952, resulting in a simplified interior layout while maintaining the original exterior appearance.

Currently, the building houses multiple institutions, including the Federal Agency for Civic Education. While the exterior maintains its original appearance, the interior spaces have been modernized for contemporary use. The building now accommodates various governmental and cultural organizations.

As part of the Upper Middle Rhine Valley, the building holds designation as a UNESCO World Heritage Site. Its current function represents a transition from its original role as a seat of regional governance.
