Rýzmburk castle, Gothic castle ruins in Osek, Czech Republic
Rýzmburk is a Gothic castle ruin in Osek composed of a central residential section with towers and a larger defended perimeter created by rampart walls. The standing structures and remains show the original medieval layout and construction techniques used to build this fortified complex.
The structure was founded between 1241 and 1250 by Bohuslav I and completed by his son Boreš II of the Hrabišici family. This fortress served as a seat for the noble family during the early High Middle Ages in Bohemian territory.
The ruins have drawn visitors seeking the quiet presence of medieval stone and the feeling of a place left behind by time. Today, people come to walk among the walls and imagine what life was like in these structures centuries ago.
The ruins are accessible through marked trails starting from the town of Osek and work well for a day visit. Wear sturdy footwear since the ground is uneven in many areas and some sections require climbing over rocky terrain.
A massive Gothic tower known as the zephyr rises from the ruins and ranks among the largest fortification structures of its kind in northern Bohemia. This prominent structure is visible from many points around the site and makes the ruin recognizable from a distance.
