Remains of the Castle in Stopnica, Medieval castle ruins in Stopnica, Poland

The Remains of the Castle in Stopnica is a rebuilt two-storey building in the western part of the town, reconstructed in 2011 from archival photographs mostly from the 1930s. It stands on the site of a royal castle founded around 1350 by King Casimir the Great, later rebuilt as a Baroque palace in 1783 by starosta Eliasz Wodzicki. The present building houses the Gmina Cultural Centre.

King Casimir the Great built a royal castle here around 1350, described by Jan Długosz as a stone manor. Władysław Jagiełło stayed five times between 1405 and 1414, and Queen Jadwiga twice. In 1783 Eliasz Wodzicki rebuilt it as a Baroque palace; it burned in 1944 and was reconstructed from 1930s photographs, reopening in January 2011.

The remains show how medieval fortifications were built into the landscape, with the location beside the river being central to how the castle functioned. Visitors walking through the site can see how the structure relates to the natural surroundings and understand the practical design of such buildings.

The site is accessible via National Road 73 and lies roughly 17 kilometers east of Busko-Zdrój in Świętokrzyskie Voivodeship. The grounds are open ruins, so visitors should wear suitable shoes and watch their footing on uneven surfaces.

The castle was rebuilt in 2011 using photographs and archival material mostly from the 1930s, and since January 2011 it has housed the municipal cultural centre. The municipality bought the burnt-out building in 2004 from a bankrupt horticultural and beekeeping cooperative that had used it as a fruit and vegetable collection point.
