Graurheindorfer Straße 157

Graurheindorfer Straße 157 is a brick structure with curved gable roofs and ornamental facade details from the early 1900s. Four main halls form the core of its layout, creating a substantial rectangular footprint across the site.

The structure was built in 1905 following designs by the city's engineering office to serve as a tram depot. It operated for roughly 80 years before tram services ended in 1986 and the facility transitioned to other uses.

The building now houses the headquarters of a major education coordination body that works across German states. Visitors can see how it functions as a modern administrative center while maintaining its distinctive historical facade.

The building is now an office complex in Bonn-Castell, which means public access inside is limited. The exterior architecture and facade details can be viewed freely from the street at any time.

The central gables feature semicircular stucco details with railway-inspired technical motifs at their upper sections. Part of the left front gable was demolished in 1973, giving the structure an unexpected asymmetrical character.
