In 1170, Count Henry I of Arnsberg donated money for the construction of Wedinghausen Monastery for sin of fratricide. Church of St. Lawrence in the monastery, apparently, was originally built in the Romanesque style. But in 1210 the first building of the church was completely destroyed by fire and was rebuilt in the Gothic style. The church was finally built in 1350. Its authority is evidenced by the fact that from 1794 to 1803 the relics of the Cologne Cathedral were kept in it!
After the secularization of the monastery in 1803 the local authorities adapted it - or rather, what was left of it after the demolition of two wings - to the needs of the city: a secular school and a library were established. And the Church of St. Lawrence became parochial. People visit the temple to see the apse with the XIII century stained-glass window, the altar of the Virgin Mary, a luxury Baroque chair, the XII century Romanesque crucifix, transferred here from the chapel of Arnsberg’s castle. One of the sculptures depicts the monastery founder, Count Henry I, in religious habit with a miniature church in his hands.
