Mitchelstown Cave, Co Tipperary, Ireland.
One of Europe's major show caves. Discovered in 1833 by Michael Condon who was quarrying limestone when his crowbar sliped into a crevasse. He removed a few boulders to retrieve the bar, next minute he found himself looking down into a network of passageways. In order to preserve the caves natural state guided tours were started and to this day visitors follow in Michael Condons footsteps and visit caverns surrounded by indescribable cave formations
