Buda Castle is the historical castle and palace complex of the Hungarian kings in Budapest, and was first completed in 1265. Buda Castle was built on the southern tip of Castle Hill, bounded on the north by what is known as the Castle District, which is famous for its medieval, Baroque, and 19th-century houses, churches, and public buildings. The castle is a part of the Budapest UNESCO World Heritage Site.
The first citizens arrived to Castle Hill in the 13th century after the Mongolian invasion, seeking protection in the hills of Buda. The first royal castle was built around this time. The golden age of Castle Hill was in the 15th century, following the marriage of King Matthias Corvinus and Beatrix of Naples in 1476. Many Italian artists and craftsmen accompanied the new queen, and Buda became an important European city. After the Turkish occupation, Buda was in ruins. A Baroque city was built, and Castle Hill soon became the district of government. During World War II, Buda was bombed to the ground and had to be rebuilt again.
Though Castle Hill has changed much since building began in the 13th century, its main streets still follow their medieval paths. Some houses date back to the 14th and 15th centuries, giving us an idea of what the Castle District may have looked like back then. Practically every house has a plaque indicating the century in which it was built, and providing details of its history. A surprising number of the buildings are still private homes, as Castle Hill is also a residential area.
Buda Castle Hill is also home to a large interconnected cellar system that consists of natural caves created by thermal waters and man-made passageways. Inhabitants have used the caverns for centuries for storage and shelter. The earliest traces of human life found here are 500,000 years old.
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.
