Šomoška Castle is unique among the Slovak castles as it is built of unconventional hexagonal basalt pillars. It was probably built in the later half of the 13th century after the Tartar invasion. After suppression of the Rákoczis rebellion, the Emperor had pulled down several castles, but Šomoška was spared. However, it gradually decayed and the last tower burnt in 1826 when a lighting struck it. In 1972 extensive conservation and partial reconstruction saved the castle before its total destruction.
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.
