Two caves of the National Park are reputed to be one of the bests: Baradla-Domica is the longest (25 kilometres) with stream, while Szilice is the lowest-situated ice cave being explored around the world. Furthermore, many of the caves offer some specialty. For example, inside the Peace Cave there is a sanatorium where people suffering from asthma are treated.
The fossils of Rudapithecus hungaricus has turned up from this region. The first written documentation about the caves are from 1549. Most of the villages are exist since the Middle Ages. In this area we can find Hungary’s biggest castle at Szádvár which was built in 1250.
The Aggtelek National Park has been part of the World Heritage since 1995.
