The Cathedral Basilica of St Stanislaus and St Ladislaus of Vilnius is the main Roman Catholic Cathedral of Lithuania. It is situated in Vilnius Old Town, just off Cathedral Square. Dedicated to Saints Stanislaus and Ladislaus, the church is the heart of Catholic spiritual life in Lithuania.
The coronations of the Grand Dukes of Lithuania took place within its confines. Inside its crypts and catacombs are buried many famous people from Lithuanian and Polish history including Vytautas, his wife Anna, his brother Sigismund, his cousin Švitrigaila, Saint Casimir, Alexander Jagiellon, and two wives of Sigismund II Augustus: Elisabeth of Habsburg and Barbara Radziwiłł. The heart of the Polish king and Grand Duke of Lithuania Władysław IV Vasa was buried there upon his death, although the rest of his body is buried at the Wawel Cathedral in Kraków.
Inside, there are more than forty works of art dating from the 16th through 19th centuries, including frescoes and paintings of various sizes. During the restoration of the cathedral, the altars of a presumed pagan temple and the original floor, laid during the reign of King Mindaugas, were uncovered.
