Molnár János Cave, Underground thermal cave system in Budapest, Hungary
The Molnár János Cave extends over 6 kilometers beneath Budapest, featuring passages filled with thermal water from natural springs in limestone formations.
In the 19th century, pharmacist János Molnár investigated the dry sections above Lake Malom, leading to the discovery of this extensive cave network.
Scientists regularly conduct research in the cave to study geological processes, water chemistry, and newly discovered species in this subterranean environment.
The cave entrance is located near Lake Malom, with guided tours available for visitors interested in exploring the accessible sections of this thermal system.
Water temperatures in the cave maintain a constant 20-25 degrees Celsius throughout the year, supporting specific mineral formations and biological processes.
