Cathedral with five chapels. This second cathedral, however, burnt down in 1419. During preparations for his 1429 coronation as King of Lithuania, Vytautas built a significantly larger Gothic Cathedral in its place. Although the coronation never took place, the walls and pillars of this third Cathedral have survived to this day. The third Cathedral had three naves and four circular towers at its corners, and Flemish traveler Guillebert de Lannoy noticed its similarity to Frauenburg Cathedral. In 1522, the cathedral was renovated, and a bell tower was built on top of the Lower Castle defensive tower. After another fire in 1530, it was rebuilt again and between 1534 and 1557 more chapels and the crypts were added. The cathedral acquired architectural features associated with the Renaissance. In 1529, the Crown Prince and future King of Poland, Sigismund II Augustus, was crowned Grand Duke of Lithuania in the cathedral. After yet another fire in 1610, the cathedral was rebuilt again, and the two front towers were added. The cathedral was damaged again in 1655 when Vilnius fell to Russian troops in the Russo-Polish War of 1654–1667. It was renovated and redecorated several more times. Between 1623 and 1636, at the initiative of Sigismund III Vasa and later completed by his son Wladyslaw IV Vasa, the Baroque style Saint Casimir chapel by royal architect Constantino Tencalla was built of Swedish sandstone. Its interior was reconstructed in 1691–1692 and decorated with frescoes by Michelangelo Palloni, the altar and stuccowork by Pietro Perti. This chapel contains sculpted statutes of Jagiellon kings and an epitaph with Wladyslaw IV Vasa's heart. More than anything in the Cathedral this chapel symbolizes the glory of Polish-Lithuanian union and common history. In 1769 the southern tower, built during the reconstruction of 1666 collapsed, destroying the vaults of the neighbouring chapel and killing 6 people. After the damage, Bishop of Vilnius Ignacy Jakub Massalski ordered the reconstruction of the cathedral. The works started in 1779 and were completed in 1783, and the interior was completed in 1801. The cathedral was reconstructed to its present appearance according to the design of Laurynas Gucevičius in the Neoclassical style; the church acquired a strict quadrangular shape common to local public buildings. The main facade was adorned with sculptures of the Four Evangelists by Italian sculptor Tommaso Righi. Some scholars point to the architectural resemblance of the cathedral to the works of Andrea Palladio
