Hohenzollern Building, Colonial architectural monument in Swakopmund, Namibia.

The Hohenzollern Building is a national monument in Swakopmund, built in 1904–1906 in a historicist Neo-Baroque style for Hermann Dietz, whose initials HD are still visible on the northern gable. The facade carries ornate detailing, and an Atlas figure holding a globe sits above the entrance.

Hermann Dietz built the Hohenzollernhaus between 1904 and 1906 in the Neo-Baroque style, and his initials HD remain on the northern gable. It later housed the Hohenzollern Hotel, which fared poorly, so Dietz rented parts of the building to the Swakopmund city administration. In 1972 it was declared a National Monument, and it now serves as owner-occupied flats.

The building displays German colonial architecture with Bavarian design elements that remain visible today. These style features shape Swakopmund's streetscape and reflect the European past of the city.

The building sits at the intersection of Libertina Amathila Avenue and Tobias Hainyeko Street in the city center. The location is easy to find and visible from the street for exterior viewing.

The initials "HD" on the northern gable still commemorate Hermann Dietz, who built the house for himself between 1904 and 1906. The Atlas figure above the entrance is a later replacement: the original cement version weathered away and was renewed in 1988 in plaster of Paris.
