The Cathedral of Vilnius has been rebuilt several times throughout history, reflecting Gothic, Renaissance, and Baroque architectural styles. It was reconstructed in 1783 in the Neoclassical style, becoming a grand and symmetrical building with 11 side chapels. The bell tower dates back to the 14th century and was later expanded. St. Casimir's Chapel and sacristy rise at the eastern end, while colonnades line the sides. The main facade features sculptures and statues, as well as an underground catacomb. The Cathedral serves as the center of Catholic spiritual life in Lithuania.
