Baradla–Domica Cave System: A connected cave system extending across Hungary and Slovakia, known as Baradla in Hungary and Domica in Slovakia. This cross-border system is the property’s best-known cave and a defining example of its shared geology.
Karst: A landscape formed as soluble rock dissolves, producing features such as caves, sinkholes, and underground drainage. The property is a major example of this landscape-forming process in limestone.
Pannonian Basin: A large sedimentary basin in Central Europe, surrounded by the Carpathians and other mountain ranges. The karst lies within the broader geological setting of the Pannonian Basin.
Speleology: The scientific study and exploration of caves, including their geology, hydrology, biology, and archaeology. Research on the extensive cave systems draws on this interdisciplinary field.
World Heritage List: UNESCO’s register of cultural and natural properties recognized as having outstanding universal value. Inscription identifies the caves as heritage whose value extends beyond national boundaries.
Baradla Cave: A major limestone cave in Hungary’s Aggtelek Karst, forming part of the Baradla–Domica system. Its extensive passages and underground formations anchor the Hungarian side of the property.
Limestone: A sedimentary rock composed chiefly of calcium carbonate, often formed from accumulated marine remains. Its soluble bedrock is the material from which the region’s karst caves developed.
Aggtelek National Park: A national park in northeastern Hungary that protects part of the Aggtelek Karst. Its establishment protects the Hungarian landscapes included in the World Heritage property.
Cave Conservation: The protection and management of caves and their geological, biological, and cultural features. Fragile formations and underground habitats require protection from damage and disturbance.
Transboundary Protected Area: A protected natural area that spans or links territories governed by more than one country. The property’s geology crosses the Hungary–Slovakia border, requiring coordinated protection.
