The Protestant St. Martin's Church in Brunau is very interesting in terms of cultural history and architecture. It was built around 1200 in the Romanesque style from field stones and later received two different spires on the transverse tower, one in the shape of a cone and the other in the shape of an eight-sided pyramid, made of brick in the Gothic style. Legend attributes this circumstance to two daughters of the Alvensleben family from Plathe, who could not agree on the shape of the spire. Finally, they each had a tower built. There is a tower bell in front of the church.
