Ruins of the medieval Divín Castle can be seen above the village. The castle was built by the end of the 13th century and it played an important role as an anti-Turkish fort in the 16th century. Its ill-famed owner Imrich Balassa, robber knight seated here in the 17th century and undertook assaults in its environs. After his death, the Castle was conquered by the Imperial troops in 1683 and fell in decay. Only parts of some walls survive.
Fortified and likewise abandoned Renaissance manor house, Baroque church and the building of parsonage with the oldest sundial in region of Novohrad are in Divín. Interesting events are organized here in summer months.
References:Varberg Fortress was built in 1287-1300 by count Jacob Nielsen as protection against his Danish king, who had declared him an outlaw after the murder of King Eric V of Denmark. Jacob had close connections with king Eric II of Norway and as a result got substantial Norwegian assistance with the construction. The fortress, as well as half the county, became Norwegian in 1305.
King Eric's grand daughter, Ingeborg Håkansdotter, inherited the area from her father, King Haakon V of Norway. She and her husband, Eric, Duke of Södermanland, established a semi-independent state out of their Norwegian, Swedish and Danish counties until the death of Erik. They spent considerable time at the fortress. Their son, King Magnus IV of Sweden (Magnus VII of Norway), spent much time at the fortress as well.
The fortress was augmented during the late 16th and early 17th century on order by King Christian IV of Denmark. However, after the Treaty of Brömsebro in 1645 the fortress became Swedish. It was used as a military installation until 1830 and as a prison from the end of the 17th Century until 1931.
It is currently used as a museum and bed and breakfast as well as private accommodation. The moat of the fortress is said to be inhabited by a small lake monster. In August 2006, a couple of witnesses claimed to have seen the monster emerge from the dark water and devour a duck. The creature is described as brown, hairless and with a 40 cm long tail.
