Hochhaus Glückauf, Historic high-rise building in Südstadt-Bult, Hannover, Germany.

The Hochhaus Glückauf is a nine-storey clinker-brick building completed in 1930 at Geibelplatz 5, closing the eastern end of Geibelstraße. Its five-axis facade is centred on a six-storey triangular bay window above a pointed-arch arcade, and the middle axis carries a life-size miner sculpture and a keystone with the mining symbol of hammer and pick.

Constructed during the interwar period by architect Wilhelm Ziegeler for coal merchant C. Lichtenberg, this building represents Hannover's urban development efforts to address housing shortages during the economic challenges of the early 1930s.

The building's name 'Glückauf' references the traditional German miner's greeting meaning 'good luck,' with mining symbols including hammer and pick carved into the keystone and a life-sized miner sculpture adorning the facade.

Currently designated as an architectural heritage monument under Lower Saxony's preservation laws, the building continues to serve as residential housing while maintaining its original structural integrity and historical character.

The entrance pathway features the word 'Glückauf' inlaid in mosaic cobblestones, making it one of the few buildings in Hannover where mining heritage is literally embedded into the street-level approach.
