The International Show Caves Association (I.S.C.A.) was founded in November 1990 and set up its central office in Genga, Italy.
After the first Consitutent Assembly held in Frasassi (Genga Ancona, Italy) in November 1989, important events have contributed to the development and consolidation of the association.
A show cave is defined as a natural occurring void beneath the surface of the earth that has been made accessible to the public for tours.
