The Cathedral Basilica of St Stanislaus and St Ladislaus of Vilnius (also known as Vilnius Cathedral; ; , historical: Kościół Katedralny św. Stanisława) is the main Catholic cathedral in Lithuania. It is situated in Vilnius Old Town, just off Cathedral Square. Dedicated to the Christian 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 (1430), his wife Anna (1418), his brother Sigismund (Žygimantas) (1440), his cousin Švitrigaila (1452), Saint Casimir (1484), Alexander Jagiellon (1506), and two wives of Sigismund II Augustus: Elisabeth of Austria (1545) and Barbara Radziwiłł (1551). 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. In addition, the remains of the cathedral built in 1387 were also located. A fresco dating from the end of the 14th century, the oldest known fresco in Lithuania, was found on the wall of one of the cathedral's underground chapels. During the Soviet regime, initially the cathedral was converted into a warehouse. Masses were celebrated again starting in 1988, although the cathedral was still officially called The Gallery of Images at that time. In 1989, its status as a cathedral was restored. History It is believed that in pre-Christian times, the Baltic pagan god Perkūnas was worshipped at the site of the cathedral. It has also been postulated that the Lithuanian King Mindaugas ordered the construction of the original cathedral in 1251 after his conversion to Christianity and appointment of a bishop to Lithuania. Remains of the archaic quadratic church with three naves and massive buttresses have been discovered underneath the current structure in the late 20th century. After Mindaugas's death in 1263, the first cathedral again became a place of pagan worship. In 1387, the year in which Lithuania was officially converted to Christianity, construction began on a second Gothic
