Consisting of a church, monastery, belfry and beautiful rococo gate, with the exception of the latter much of it in a state of hideous disrepair, the Holy Trinity Church originally dates from 1514 and features elements of Gothic, Baroque and Neo-Byzantine architecture. Built at the behest of the Belarusian national hero Konstantin Ivanovich Ostrozhsky (Konstantinas Ostrogiškis, ca. 1460-1530), the church, which was extensively altered after a serious fire in the middle of the 18th century, belongs to the Uniates or Eastern Catholic Church, a peculiar faith which fuses together many Orthodox beliefs whilst recognising the Pope as God’s representative on Earth. The church is a complete mess inside, almost completely empty with the exception of some wonderful, barely visible frescos both inside and out. There’s also a small chapel on the right as you enter. Renovation work is slow. The elaborate, 17.9m gate was built in 1761 to a design by Johann Christoph Glaubitz (Jonas Kristupas Glaubicas, ca. 1700-1767).
