The Gothic Roupov castle was founded in the 13th century, and after a Renaissance modernization was one of the most beautiful Czech castles. The now completely standing part was built later and is being used by the current owners, the old ruined part hides many original architectural pieces, and is freely accesible. The original black kitchen with a medieval chimney is still present, and a gothique well. The castle was in usable state in the late 18th century, but slowly deteriorated, and the old part was disassembled for stone when a nearby village burned down and building material was needed. Some walls collapsed in 1817 and the castle became a ruin. Today the old part is conserved.

The monument is located in the valley of Le Loir. Its gardens have evolved throughout the centuries.
