Rotštejn is a ruined rock castle founded sometime around 1250. It is situated in the south-eastern part of Klokočské skály rocks.
The castle was founded in the mid-13th century as the seat of the House of Rotštejn. Part of it was carved into the surrounding sandstone rocks; the rest was built onto the rocks. It was rebuilt after a fire in 1318 and boasted a large walled palace. Another dominant feature of this manorial residence was its impressive tower with a half-timbered structure built onto it, several storeys high. The castle fell into ruin in the early 15th century. At the beginning of the 17th century people carved out dwellings at the foot of the rocks, and built cottages on in front of them. These dwellings were still used with varying intensity at the end of the 19th century.
The parts that have remained until the present day are the remnants of the palace walls, a section of a passageway, the well, and the relic of the black kitchen.
Sheds, stables and cellars have been preserved from the village settlement.
