Right on the water, the city’s Gothic Revival fish auction house was repurposed as a maritime museum in 1978. The interior has been whitewashed and in this airy space is an exhibition on Kiel’s fishing and seafaring history.

One exhibition here charts the construction of the Kiel Canal, which was completed in 1895 and connected the North Sea with the Baltic.

There are logbooks, maps, model ships, navigation instruments and a cross-section of the Seehund midget submarine from the Second World War.
