This Gothic and Renaissance building on the corner of Długa and Długi Targ was the seat of city government until 1921 and now houses a Museum of Gdańsk branch. Upstairs is the Red Hall, the grand chamber where the city council met. The building also hides the oldest door in Gdańsk, cellars and hidden passages. In summer, the tower's viewing gallery about 50 meters up looks over the old town.
