Schloss Trumau

Schloss Trumau is a fortified manor house in Austria with a square layout and three round towers surrounded by water channels. The building now houses an international theological institute that relocated there in 2009.

The estate was given in 1138 by Margrave Leopold IV to Heiligenkreuz Abbey, where Cistercian monks built the fortified structure. Soviet forces occupied the castle from 1945 to 1947, causing significant damage during their use as a military communications center.

The castle chapel displays a painting of the Coronation of Mary that replaced the original 1702 work by Johann Michael Rottmayr. The site maintains religious significance through its current use and connection to the abbey that shaped its early development.

The castle is not open for individual visits as it operates as a private educational institute. Those interested in viewing it should inquire about special occasions or events that may allow public access.

The castle served as a Soviet communications center from 1945 to 1947, a period when valuable artworks including a Rottmayr painting were lost. This occupation left visible marks on the building that reflect a dramatic chapter in its past.
