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 of 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 Władysław IV Vasa was buried there upon his death, although the rest of his body is buried at the Wawel Cathedral in Kraków.
