A small Gothic knight’s castle in Oporów belongs to one of the most valuable monuments of medieval fortified architecture in central
Poland. Its construction was begun already in 1425 by the voivode of Leczyca – Mikolaj Oporowski and continued by the archbishop of Gniezno – WladysΠaw Oporowski. The building on a square plan with two fortified towers is placed on a manmade island surrounded by a moat. According to a legend the ghost of castellan’s of Oporów daughter – the White Lady haunts the castle.
Since 1947 the castle has housed the museum exhibiting works of art and artistic craftwork from the 16th to the 19th centuries.
