The castle in Levice was built in the 13th century, when the near Tekovsky castle’s importance had declined due the devastation of Tartars. It was built on andesite rock, the remnants of Neogenic volcanic activity, which extended to the Štiavnica hills. The west side of the castle was bounded by the marshy meadow of the river Hron, with its several river branches. The castle itself had been a fortress for protection of the mining towns. Under the protection of the castle in the 14th century a settlement known as 'Big' or 'Old Levice' had been established, which is the real predecessor of today’s Levice town.
The 150 year long Turkish occupation, which started in the 16th century, weakened the town economically and made it more dependent on the castle’s estate. At this time the Levice castle, then already a royal castle, was listed among the 15 most important defence forts. In the middle of the 17th century the Turkish incursions grew stronger. Seeing the enemy’s huge numerical advantage, the captain gave up Levice without resistance. The Turks' rule in Levice lasted for only 224 days, when in 1664 by an unexpected action they were expelled out of the town. After the end of the Turkish wars Levice lost its important role as a frontier-castle and in 1699 in accordance with official orders it was abolished as a fort.
Frequent fires meant great disasters for Levice. In 1696 fire destroyed almost the whole town. In 1715 there were 195 taxpayers and 43 craftsmen in the town. In the time of Rákoczy’s Revolt in the 18th century the castle was in a very bad condition. In order to prevent from being used for military purposes the rebels decided to destroy it before leaving. The castle was never re-established and thus it lost its military importance.
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.
