Bryggen, the old wharf of Bergen, is a reminder of the town's importance as part of the Hanseatic League's trading empire from the 14th to the mid-16th century. Many fires, the last in 1955, have ravaged the characteristic wooden houses of Bryggen. Its rebuilding has traditionally followed old patterns and methods, thus leaving its main structure preserved, which is a relic of an ancient wooden urban structure once common in Northern Europe. Today, some 62 buildings remain of this former townscape. - UNESCO
