Haus der Seefahrt, Hamburg commercial office building from 1910

Haus der Seefahrt is a sandstone-clad reinforced concrete skeleton building with Jugendstil ornament, built 1909–1910 as a Hamburg Kontorhaus. Its main facade has twelve narrow window axes in three pilaster-divided sections; a shallow bay from the second to fourth upper floors is crowned by a grille of two swimming swans, with a frieze of sea creatures and a crocodile below. At the southeast corner stands a bronze Hammonia with a lion and angel figures on a sandstone base.

Built in 1909–1910 to plans by Edgar Foßhag and Georg Schlepps for the client F.W.G.H. Fischer, the house was let as a Kontorhaus for trading and shipping firms; other trades followed later. A 1991 renovation by the Winking/Froh office converted it into flexible office floors and inserted a new staircase, while the outer facades kept their original form.

The building's name reflects the sea-themed sculptures adorning its facade, including swans and marine creatures carved into the stone. These decorations show how deeply the sea and maritime trade shaped Hamburg's identity and how the city honors that heritage through its architecture.

The building stands at Hohe Brücke 1, between Deichstraße to the west, Hohe Brücke street to the south and the Nikolaifleet to the east. The bronze Hammonia figure sits on the south-east corner, so walk that side to see it. The 1991 renovation added a new staircase inside; the outer facades kept their original form.

At the southeast corner, a bronze figure of Hammonia, Hamburg's city symbol, carries a flag over her shoulder and raises her left arm to the sky, with a lion walking behind her. The sandstone base is held up by angel figures whose wings support the scene above.
