First completed in 1340, the high, light hall church has the mightiest Gothic church tower in Westphalia, although the helm roof has been missing since a hurricane in 1704. The beautiful sculptures of the Figurenportal (figure door), destroyed by the Baptists, were discovered under the transept and can today be seen in the Landesmuseum (City Museum). The church is also known as the Überwasserkirche (Overseas Church), since it was on the far side of the Aa River from the town.
