Sloup Castle (Czech: Perkenstein or Pirkštejn; German: Einsiedlerstein or Bürgstein) is a rock castle in the municipality of Sloup v Čechách, in the Liberec Region of the Czech Republic. It takes its name from the special appearance of the freestanding 35-metre (115 ft) high sandstone rocks (its name literally means "column"), into which it was carved in the 14th century. The castle was first mentioned in records dating from 1324 owned by Čeněk of Ojvína. It was established beside a salt trade route from Meissen to Česká Lípa by the Ronovec family. The edges of the outcrop, which was a level summit, were carved to resemble castle walls with loopholes, and some of the gullies in the outcrop were filled in with masonry. Thanks to an ingenious system of trenches it was possible to flood the area around the rocks. The combination of natural conditions and human ingenuity turned the castle into a fortress unassailable by medieval warriors. More information...
