St. Andreas Church is a listed building in Ostönnen. Its Gothic organ is one of the oldest playable organs in the world, probably dating from the first half of the 15th century. The church in Ostönnen was first mentioned in a document in 1169. Excavations have revealed the existence of two earlier churches. While the west tower dates from the first half of the 12th century and comes from an earlier building, the older nave was replaced in the second half of the 12th century. In 1979, the entire building was plastered and repainted in the presumed original colour.

St. Reinoldi, or Reinoldikirche, is a Protestant church located in the city center of Dortmund. The oldest part of the building is the transept, built just before the middle of the 13th century.
