Baradla cave

The Baradla Domica cave system is a large cave system in northern Hungary. As part of the Aggtelek Karst, it extends more than 25.5 km (25, 500 m) and includes the 5.3 km (3.3 mi) Domica Cave. A significant part of the cave has varied colors and shapes providing an unparalleled spectacle of decorative stalactites. The cave system has been visited and researched for centuries because of its famous ornate speleothems. Natural entrances to the cave have been open from ancient times, and there are traces of Neolithic occupation. However, the first written mention of the cave dates from 1549. The first survey was conducted in 1794 by Joseph Sartory. In 1825 it was only known to be 1.8 km (1.1 mi) in length. This section was surveyed in 1802 and the first map published. In 1825 the engineer, Imre Vass explored the cave a further 5 km (3.1 mi) along the main branch, producing an accurate map and a description. His work, published in Hungarian and German was published in 1831. In order to facilitate cave visits, the first tourist walks were installed in 1806. In 1890 the Red Lake entrances were established and further exploration and extension was conducted between 1927 and 1928.
