Gothic-style Church from the second half of 15th century. Originally a monastery. Architect’s findings prove that the oldest part of St. Andrew’s Church (the presbytery) was constructed during this period and its main body at the turn of 14th and 15th centuries.
It’s a three nave building with a hall arrangement, with a taller and wider nave and a lower and narrow polygonally closed presbytery. The vesrty is attached to the main building and a 19th century porch from the west side. A gothic groin vault remained in the presbytery. In the main-classical style altar (from around 1780) there is a crucifix from this period and sculptures of St. John and the Virgin Mary on the sides. In narrow side-naves there are currently two Baroque altars. In the right one, there is a painting of the Holy Family from the beginning of the 18th century and another, smaller painting of St. Valery Anthony of Padua. Opposite the nave, there is a second side altar with a painting of The Virgin Mary with a Child from the second half of 18th century and a small painting of John of Nepomuk next to it. An interesting historical site is a Baroque epitaph founded in 1790 by Władysław Gurowski (Great Marshal of Lithuania) – the owner of Kleczew at the time.
