The Hölloch Cave is the fourth longest caves in the world. It is situated in Switzerland
, in the valley of the river Moutha. The Hölloch Cave is 194 km long and about 950 m deep. It was discovered in 1875 by Alois Ulrich, who noticed that sometimes a strong current springs at the bottom of the usually dry gorge called Hell. After surveying the gorge, he discovered an entrance into an unknown cave, which he named after the nearby gorge Hölle Loch (Hell's Hole) . The Hölloch Cave was opened to the public in 1905. It was considered to be the longest cave in the world until the discovery of the Mammoth Cave
. The local speleologists are currently trying to connect the Hölloch Cave with the Silberen Cave. If they succeeded, it would create an underground space with a length of 230 km.
