Cathedral of the Holy Trinity

The Catholic Cathedral of the Holy Apostles Peter and Paul was built between 1616 and 1780 and belonged to the Jesuit order. The architect M. Gints drew up the plan of the building, which was later completed and modified by architect Djakomo Briano. In the second half of the 1630s, the construction of the church in the Renaissance style was completed. On 14 June 1724, a fire broke out and severely damaged the church. In the following years, until 1730, a thorough restoration was carried out with the help of the architect Paweł Giżycki, a Jesuit. In order to preserve the walls weakened by the fire, the church was built with the galleries around the narthex, two towers were erected. The church took on a classical appearance. In 1773, Pope Clement XIV announced the abolition of the Jesuit order. In 1787, the church was elevated to cathedral status.

The Great Synagogue in Lutsk was constructed in 1629 as a fortress synagogue. It was the religious, educational, and community centre of Lutsk until it was partially destroyed in 1942 as part of World War II. The synagogue was restored in the 1970s and is now used as a sports club.
