Thierstein Castle (Ruin)

The Thierstein Ruin, once a castle, now stands on a mountain spur above the village of Thierstein in Bavaria. Its history is closely linked to the Notthaffts and the conflicts over the Egerland.
History+
The first mention of Thierstein Castle dates back to 1340. It was built by Albrecht XI. Notthafft as an administrative seat, after his father, Albrecht VI. Notthafft von Wildstein, had been appointed Imperial Forester in the Egerland by King Henry VII in 1310. The Notthaffts became embroiled in lengthy feuds with the city of Eger, which also claimed the forester's office. To finance these conflicts, they had to gradually sell off their possessions. By the end of the 14th century, Thierstein Castle passed to Margrave Wilhelm I of Meissen and came into the possession of the Hohenzollerns in 1415. During the Bavarian War in 1462, the village of Thierstein was set on fire by the then bailiff to deny enemy troops cover. The castle's keep became part of a defense system in 1497. In the War of the Schmalkaldic League in 1553, Bohemian troops occupied the complex.
