Krzepice Castle, Medieval royal castle in Krzepice, Poland.

Krzepice Castle no longer exists: a small royal brick castle built in the mid-14th century, rebuilt in Renaissance style in the 16th century and ringed by bastion fortifications in the 17th century. Its ruins were demolished around 1840 on the orders of the Russian authorities and sold as building material at auction. The site of the former castle now belongs to a private owner.

King Casimir III commissioned the fortress in the 14th century as both a border stronghold and royal residence. It maintained strategic importance throughout the medieval period as a key position between competing regional powers.

The site has revealed pottery fragments, metal objects, and household items through excavations, showing how people lived and worked within its walls across different eras.

Access to the site is limited due to its private status and visitors cannot explore the interior freely. Walking around the exterior perimeter offers a sense of the structure's scale and position within the landscape.

A rare historical map of the fortress was discovered in Swedish archives dating to the early 1700s. It provides valuable evidence about the physical layout during that period and how the structure appeared centuries ago.
