Moored on the Göta älv in the middle of the city is a mini-armada of 15 heritage vessels.

These come in all shapes and sizes and make up a floating museum, plunging you into Sweden’s military and civilian seafaring heritage.

The two standout craft you can board are the HSwMS Småland, a Halland-class destroyer launched in 1952, and the HMS Nordkaparen, a submarine in service from 1962 and famously almost involved in a collision with a Soviet submarine in 1980.
