The first documented mention comes from a deed of donation from the year 1021.
When large areas of the country were depopulated after the Ottoman invasion in 1529, Croats were settled. These formed the majority of the population for centuries. The castle, which was destroyed during the raids, was rebuilt by Count Salm from 1550 onwards. The so-called Neuschloss was built by Count Auersperg in 1679.
