Vytautas' the Great Church of the Assumption of The Holy Virgin Mary (Vytauto Didžiojo bažnyčia) is one of the oldest churches in Kaunas. The church was built on the north bank of the Neman River around 1400 for Franciscan monks and foreign merchants. It was ordered and funded by Vytautas the Great as a commendation to the Blessed Virgin Mary for saving his life after a major defeat in the Battle of the Vorskla River.
Being quite close to the river the church has suffered many times from spring floods. In 1812 it was burned by French troops. The Franciscan monastery was closed by Russian administration after the November Uprising. In 1845 the Catholic Church was closed and later was rebuilt and reopened as an Orthodox church. From 1903 it served as military barracks. In 1915 Germans organised a warehouse here. The building returned to the Catholic Church in 1919 and underwent major renovation works in 1931–1938, and again in 1978–1982.
The church was constructed in Gothic style and is an example of the Lithuanian Brick Gothic architecture. The church layout of the Latin cross is unique in the Lithuanian Gothic. Over the years the ground level around the church has been raised significantly and the façades became lower; to compensate for this, the windows were shortened and the side portals were removed. The bell tower was added later and has probably been used to guide ships navigating the Neman River.
Lithuanian writer Juozas Tumas-Vaižgantas (1869–1933) is buried in the crypt of the church.
References:The Church of St Donatus name refers to Donatus of Zadar, who began construction on this church in the 9th century and ended it on the northeastern part of the Roman forum. It is the largest Pre-Romanesque building in Croatia.
The beginning of the building of the church was placed to the second half of the 8th century, and it is supposed to have been completed in the 9th century. The Zadar bishop and diplomat Donat (8th and 9th centuries) is credited with the building of the church. He led the representations of the Dalmatian cities to Constantinople and Charles the Great, which is why this church bears slight resemblance to Charlemagne's court chapels, especially the one in Aachen, and also to the Basilica of San Vitale in Ravenna. It belongs to the Pre-Romanesque architectural period.
The circular church, formerly domed, is 27 m high and is characterised by simplicity and technical primitivism.
