Vorau Priory was founded in 1163 by Margrave Ottokar III. The monastery quickly became an religious and cultural center of Eastern Styria, but it was badly damaged by fires in 1237 and 1384. Vorau was located on the border to Hungary and therefore repeatedly faced military threats. The monastery was fortified and armed in the 1450s to defend the local population. The monastery was rebuilt into the Baroque style in 17th and 18th centuries. The fortifications were demolished and moat filled in 1844.
Vorau monastery was again damaged by fire in 1945 during the World War II. Today it is a conference center and parish church. There is also a notable library containing 40 000 volumes, including 415 manuscripts.
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 oldest parts of the present red-brick church are from the 1300s. In the late 1400s the church was enlarged to the appearance it has today. 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.
