The Domica cave is a karst cave situated on the south-western border of the Silicka planina Plateau 10 km (6.2 mi) south-east of Plesivec in the Rožňava District of the Košice Region in southern Slovakia. In combination with the Baradla cave, it makes up the most significant section of the Aggtelek Karst and Slovak Karst cross-border cave network that continues into the Aggtelek National Park in Hungary. The cave is well known for its complex structure and high density of speleothems. These vast limestone passages, that had formed during the Middle Triassic and are rich in speleothems were discovered in 1926 by Ján Majko. A 1,600 m (5,200 ft) section of its total length of 5,140 m (16,860 ft) has been publicly accessible since 1932. As an element of the Caves of Aggtelek Karst and Slovak Karst the site was listed as a UNESCO World Heritage Site list in 1995 because of the diversity of cave features found within it and its record of both tropical and temperate effects on karst cave formation.
