Castle ruins in Rytwiany, Castle ruins in Rytwiany, Poland

The castle ruins in Rytwiany consist of the surviving corner of a three-storey, single-bay brick building measuring 13 by 39 metres, built at the end of the 14th century, with a buttress still attached. Around 1420–1436 a rectangular defensive wall was added, along its northern section stood a second building known as the Great House. The site now forms a historical and educational park.

The castle was first documented in 1397 and underwent major reconstruction between 1420 and 1436 under Bishop Wojciech Jastrzębiec. This building phase shaped the structure visible in its remains today.

The grounds hold sculptures by Sławomir Micek depicting figures linked to Rytwiany, among them Tadeusz Kościuszko, who stayed at the castle on 19 May 1794, and Jan Tęczyński. The figures tie the ruined residence to the people who owned and used it.

The ruins are accessible from Staszowska Street, with parking available near the Volunteer Fire Department building. Signage and informational panels on the grounds help visitors navigate and understand what they are seeing.

The brick and stone walls preserve beam indentations and plaster remnants from three original levels, revealing clues about the building's former height and internal layout. These physical traces show how the structure once extended upward with multiple floors.
