The Sponeck castle was built in the late 13th century to the site of late Roman fort (built by Emperor Valentinian I around 365 AD). The castle was destroyed in the Thirty Years War. After several changes of ownership the painter Hans Adolf Buhler acquired it in 1917, rebuilt and set up a studio in the former residential tower. After the painter's death in 1951 the castle was owned by the family. Today the stone wall and two corner towers are preserved of an original Roman fort.
The first written record of church in Danmark locality date back to the year 1291. Close to the church are several stones with a Christian text and cross inscribed.

The church has been modified both internally and externally several times, among other things after the fires in 1699 and 1889. There are lot of well-preserved mural paintings in the walls.
