Ryczów Castle, Medieval watchtower ruins in Ryczów, Poland.

Ryczow Castle is a medieval watchtower ruin perched on a limestone cliff within the Polish Jura Chain. Its stone remnants include defensive walls and foundation structures that rise from the natural rock formations.

The watchtower was probably built at the end of the 14th century on the territory of Ryczów Leśny, which was mentioned in a document from 1416. It is believed to have been founded by Casimir the Great to fill a gap in the system of Jura castles. It was still in use in the 15th century.

The castle is part of the Eagles Nests Trail, connecting medieval fortresses across limestone landscapes between two major cities. Visitors walk this route to explore how defensive structures once shaped the region.

Visiting requires sturdy footwear due to rocky terrain and uneven ground throughout the site. Pay special attention when conditions are wet or muddy, as surfaces become slippery.

The sources record three villages named Ryczów — Wielki, Mały and Leśny — and the first written mention of the name dates to 1388, though it is unclear which village it concerns. Ryczów Leśny appears again in a 1416 document, and the watchtower was probably built on its land.
