The Fischauktionshalle, built in 1894, is the traditional and impressive centre of the fish market, and frequently used as a venue for special events, such as the well-deserved morning pint after making the rounds at the Fish Market. The Auction Hall with its intricate iron lattice-work design has been a listed building since 1989.
