The Hanseatic League had one of their foreign offices at Bryggen in Bergen from approximately 1360 until 1754. The Hanseatic merchants traded mainly with stockfish from Northern Norway and grain from the Baltic countries. Only German merchants were allowed to live at Bryggen during the period of the Hanseatic Office. The Hanseatics were unmarried and had to live in celibacy as long as they lived in the area. The tenements in the Bryggen area consisted of several smaller trade houses, each run by a merchant with a journeyman and apprentices. All of them lived in the house. The Hanseatic Museum shows what one of the trade houses would have been like in the last years of the German Office at Bryggen. The Hanseatic Assembly Rooms Museum is one of the oldest and best preserved wooden buildings in Bergen.
