Visit of the Cathedral of Vilnius. The first Christian church was built here in 1251, in the place of a previous pagan temple, to commemorate the baptism of Mindaugas, King of Lithuania. The church was damaged and had to be rebuilt several times during the centuries, in different styles, such as Gothic, Renaissance and Baroque, come of whose remains have survived up to our days and can still be admired. The building’s present neoclassical facade is due to the Lithuanian architect Laurynas Gucevičius, at the end of the 18th century. The cathedral’s interior contains many valuable frescos, pictures, sculptures, and tombstones. The crypt hosts a valuable fresco from the end of the 14th century, the Crucifixion, the oldest wall painting in Lithuania. St Casimir’s Chapel abounds with numerous frescos, decorative stucco works and sculptures, being one of the most valuable examples of mature Baroque architecture in Lithuania. A silver coffin, made in the 18th century, holds the remains of St. Casimir, Grand Duke and patron saint of Lithuania. The external belltower of the cathedral, a city landmark, was erected in the 15th century in the location of a defensive tower from Vilnius’ Lower Castle.
