The event ship "Herr Walter" at Speicherstraße 90 is one of the most famous and charming cultural and gastronomic locations in Dortmund's harbor. It combines raw industrial charm with a relaxed holiday atmosphere. The location is affectionately named after its last traditional owner and captain, "Herr Walter", who lived and worked on the vessel. Alongside the now-closed Solendo beach bar, Herr Walter was a pioneer in opening up the gritty, industrial Dortmund port to nightlife and the general public in 2011.

The centerpiece is a 60-meter-long, 6-meter-wide historic cargo barge built in 1901. Its former cargo hold (under deck) was completely gutted and turned into a unique, weather-proof indoor club and event space.

On the adjacent dockside, a large artificial sand beach features real palm trees, deck chairs, and sun sails, creating a holiday vibe in an industrial setting.
