The church of Our Lady, the former abbey church of a Dominican monastery, was built between the 13C and the 15C. There are traces of frescoes and a magnificent altarpiece by Claus Berg. This dates from around 1520 and has a vividly expressive style reminiscent of paintings by Pieter Bruegel the Elder. Beneath the chancel, the crypt of the original Romanesque church (1060) is the oldest vaulted building in Scandinavia.
