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.

The Jeziorsko Reservoir on the Warta River is the largest body of water in the Łódź Voivodeship, created in the 1980s for flood control and water retention purposes. Its surface area exceeds 40 km² when full and its length reaches approximately 17 km. The reservoir is an important bird habitat – it houses an ornithological reserve protecting herons, terns, and cormorants, among others (Jeziorsko Reserve and Nadwarciański Protected Landscape Area). It is also an excellent spot for observing sunsets and natural changes in the Warta Valley.

It is a Gothic building from the 14th century, founded by the Archbishop of Gniezno – Bogoria Skotnicki, rebuilt in the 16th century. As a result of the war operations in 1939, it was seriously damaged: the roof was burned down and the western gable with the vault collapsed. Right after the war (1945–1946), it was rebuilt and painted in 1958. The greatest historical value in the church is: the Gothic presbytery from the 14th century, side altars from the 17th century. In the chapel of Blessed Bogumił there is a sarcophagus made in bronze in 1667 in Gdańsk.

The original wooden church, funded by the owners of Siedlątków, the Ubyszek family, was built in the 15th century. Around 1684, a new, single-nave brick church was built in its place. Fieldstone and brick were used as materials. It was later plastered. The presbytery is rectangular in shape. The wider nave was originally two-bay. It was later extended westwards by one bay. Sections of the old façade have been preserved inside. In the presbytery, there is a barrel vault with modest stucco decoration at the seams. In the naves, there is a barrel vault with lunettes, and in the sacristy, a ceiling. The main, Renaissance altar with the miraculous painting of Our Lady of Siedlątków burned down in 1957. The current one is a copy from 1958. The side, late Renaissance altar from the mid-17th century was enriched with painted scenes from the life of St. Isidore. The second, late Renaissance side altar is dated to the mid-17th century. Other monuments of the church include: three processional crosses from the 18th century, a sculpture of St. John of Nepomuk, a Rococo monstrance from 1781, a chalice from the 17th century, a chalice from the beginning of the 17th century and chasubles from the turn of the 18th and 19th centuries. In the 1970s, the church in Siedlątków was to be dismantled and moved to another location. All because of the construction of the largest artificial reservoir in central Poland, Jeziorsko. Ultimately, it was decided to leave it on the embanked headland.

I recommend going straight to the other end of the dam and going down the stairs, where the water flows from the dam and joins the river.
