The four-storey horseshoe-shaped Bremen Tower (originally the Bremer Tower, built at the start of the 15th century) is one of the defensive structures of Tallinn Town Wall. In the 16th century, people started calling it the tower of Kampferbeck after its new owner. The Bremen Tower is linked to Bremen Gangway which connects Uus Street with Vene Street. During the renovation works at the end of the 1950s, a passage connecting the tower with Bremen's Gangway was added.
