Sts Peter and Paul Church, Lutsk
A former Jesuit church of 1616–1639, now a cathedral, with multi-level underground passages.
The Church of the Holy Apostles Peter and Paul was built for the Jesuits in 1616–1639; according to the website of the Diocese of Lutsk it was consecrated in 1639, according to Istorychna Volyn in 1639–1640. The diocese names Giacomo Briano as the designer; according to Open Lutsk, the original design was drawn up by M. Hintz and Briano probably supplemented it, while Benedetto Molli designed the college. After the suppression of the Jesuit order (1773) the church became a cathedral: according to RISU, after the fire of 1781 that destroyed the Holy Trinity Cathedral, according to Istorychna Volyn, in 1787. In 1948 the Soviet authorities turned the church into a warehouse, on 15 December 1980 a museum of atheism opened here, and on 31 March 1991 Mass was celebrated in the church again. Beneath the church lie underground passages: RISU writes of four levels, Konkurent (2020) of a drained lower level open to tourists and a merely hypothetical third.
The underground passages are shown on guided tours; address: 6 Kafedralna Street. The cathedral is in use. On 12.09.2026 russian drones attacked the railway in Lutsk (Suspilne Lutsk, 12.09.2026).
