In Zarzecze, a small town adjacent to the Pilica river, there are ruins of the stone church dedicated to Saints Valentine and Stanislaus. The church was built in the sixteenth century as part of the hospital buildings. In the seventeenth century, a brick church was built where the ministry was exercised by the fathers of the Order of Canons Regular of Saint Augustine. The property fell into disrepair after the partition of Poland, in the second half of the nineteenth century.
