Schloss Windhaag was constructed over three hundred years ago by the 17th century Austrian entrepreneur Count Joachim Enzmilner of Windhag (1600-1678). The Count was born in Augsburg and made his name and fortune by active opposition to the the Reformation and financial acuity. One of the Count’s legacies is the meticulous records of his enterprise recorded by the draughtsman Clemens Beutler. Today the castle is one of the most important cultural monuments of the Mühlviertel. A well marked walk with information boards leads to the ruins.
