History+
In the 12th century, the castle was built by the Lords of Wartenstein in the territory of the Swerzenhuntare; in 1185, a "comes de Wartstein" was documented. On March 5, 1392, Heinrich von Wartstein sold the castle with all its possessions to the Dukes Stephan, Friedrich and Johann of Bavaria; in 1394, the castle was expanded. In July 1495, the castles of Wartstein and Monsberg were destroyed. On February 18, 1508, the ruin became the property of Hans Speth von Granheim and in 1848 the property of the municipality of Erbstetten. In 1924, repair work took place, and in 1968–1970, further repair work and the addition of a spiral staircase were carried out.
