Cathedral Basilica, Vilnius. The Cathedral of St. Stanislav and St. Vladislav is the most important place of worship for Lithuania Catholics and the location for the main Christian, folk and national festivities. In 1922, the Cathedral was granted the title basilica. This is the highest church category awarded by the Pope.
Many prominent people of the Lithuanian Grand Duchy – Noblemen, Bishops and Dukes are buried in the vaults of the Cathedral. The Sovereings Mausoleum located beneath the Chapel of St. Casimir contains the remains of the Grand Duke of Lithuania and King of Poland Alexander. He is the only ruler of Poland and Lithuania buried in Vilnius. Vytautas the Great, a grandson of Duke Gediminas and the most powerful Lithuanian ruler, is buried in the vaults of the Cathedral together with his wife Ona. Two wives of Žygimantas Augustas, Queen Elisabeth of Austria (Habsburg) and Queen Barbora Radvilaitė (said to have been the most beautiful woman of her time), are also buried on the site. The walls of the Cathedral also provide shelter for the urn with the heart of King Vladislovas Vaza (Wladyslaw Vasa).
The ancient wall of the temple dating back to the 13th-15th centuries, and the oldest Lithuanian fresco painted in the 14th century, have survived in the vaults of the Cathedral.
