The main touristic highlight of Bergen is the Bryggen (or Tyskebryggen) area around the harbour in the old town. Here there are a number of Hanseatic heritage wooden commercial buildings. A number of these have been destroyed by fire over the centuries and rebuilt/restored after that. Bryggen in the past was the trading centre of the Hanseatic league in Bergen. It has been a UNESCO world heritage site since 1979.
