One block east of the Rynek is this mighty Gothic redbrick building dating from the 14th century. Its showpiece is a copy of a Romanesque portal from around 1280 on the south wall, which originally adorned the Benedictine Abbey in Ołbin, but was moved here in 1546 after the abbey was demolished. You can climb the 72m-high tower and cross the so-called Penance Footbridge.
