Benedictine monastery in Mogilno - a monastery complex founded in the 11th century, located on the Mogilinskie Lake. It was funded most probably by Kazimierz the Restorer. Currently, it is the church of the parish John the Apostle. On January 1, 2014, the monastery passed under the rule of Friars Minor Capuchins. The monastery was founded by Casimir the Restorer in the second half of the 11th century. The Benedictines were then brought back to a settlement founded two centuries earlier on a peninsula cutting into Lake Mogilin. The monks came mostly from the Rhineland and Bavaria, and the monastery received in the form of giving twenty-three towns in the vicinity of Mogilno, seven villages near Płock and the right to income from five further towns located in the region of Łęczyca. The construction of church and monastery buildings began immediately after the arrival of the monks. The objects were erected from granite and limestone available in the area. The Benedictine Mogilno Jews participated in spreading Christianity in Mazovia and Kujawy, and their community grew so much that in 1145 they took over the church of St. Jacob and the church of Saint. Klemens in Mogilno. Old monastery buildings were rebuilt in the late Romanesque style, after being destroyed by the detachments of Prince Władysław Odonica and the conflict of monks with prince Władysław Laskonogi. The hill occupied by the Benedictines was surrounded by a stone wall. In the fifteenth century, another reconstruction was made, which gave the monastery gothic features. In subsequent centuries, the political role of the monastery fell, and buildings were also destroyed. It was not until the eighteenth century that the Benedictine community began to flourish again and rebuilt the monastery complex in the Baroque style that took place in 1760-1797.
