Castle in Roztoky, Cultural monument château in Roztoky, Czech Republic.

The Castle in Roztoky is a building with traditional architectural elements located north of Prague. Inside it houses a museum that displays exhibitions about the region's history and communities.

A Gothic water fortress probably founded in the 13th century stood here; the first written mention of Roztoky dates from 1233. Reinhard of Remeš had the tower demolished at the end of the 14th century and strengthened the defences with two towers. David Boryň of Lhota bought the indebted estate in 1565 and rebuilt the fortress as a Renaissance château. The Lichtensteins held it until 1803; during the Thirty Years' War Saxon troops took the château and the top timber floor burned down and was never rebuilt.

The museum inside the castle displays exhibitions about the region's past and its people. The collections show how daily life and society in this area developed over centuries.

The location is easily accessible by public transportation from Prague. Visitors can join guided tours to learn more about the architecture and the building's features.

The castle's oldest core was a water fortress: a square tower about ten metres on each side stood on a rounded mound ringed by a wall and a moat. Reinhard of Remeš had the tower demolished at the end of the 14th century and strengthened the defences with two towers, one of them holding the gate.
