The Opaliński Castle Museum in Sieraków is housed in the rebuilt southern wing of a former fortress from the late 14th century, once owned by the Nałęcz family, and later the Opaliński family. The current building was rebuilt in the 1990s to house, among other things, the Opaliński family sarcophagi discovered in 1991. Exhibitions present the history of the Sieraków region – from archaeological finds to the present day. The building is located in the city center, near the Warta River, making it a good stopover on a cycling route. It's worth visiting the interior to see the historic coffins and learn about the region's history.

Uniejów Castle is one of the city's most important attractions, picturesquely situated on the left bank of the Warta River. Built between 1360 and 1365 at the initiative of Archbishop Jarosław Bogoria Skotnicki, it replaced an earlier wooden stronghold. For centuries, it served defensive, administrative, and residential functions, and after renovations, it gained Renaissance and Baroque elements. It is surrounded by a romantic landscape park with rare trees, perfect for strolling. Today, the castle houses a hotel, restaurant, and conference center, and the entire structure can be visited, admiring the restored interior and 25-meter-high tower.
