The town had 2 gates, 15 towers and a 2.5 km of a wall in the 13th century.

The castle in 1108 belonged to the Babenberger.

In July 11, 1683, the Second Ottoman Campaign destroyed the city along with the castle. There were a few survivors including Joseph and Michael Haydn.

In 1709, the count Löwenburg rebuilt the castle.
