History
The Lorze undercut a growing tufa mound, creating hollows and overhangs. Lime-bearing water seeping through porous tufa later formed the dripstones.
- 1863Tufa quarrying for building materials uncovered the first cave. Quarrying stopped to preserve it.
- 1885A tunnel was built to drain the underground lake into the Lorze.
- 1887The caves opened to the public.
- 1888A textile mill captured the springs in a tunnel, drying the tufa mound and stopping dripstone growth.
- 1892 and 1902Further cave sections were discovered.
Show all
- 1903Josef Leonz Schmid bought adjoining land and joined the caves to preserve the system.
- 1917A passage connected the lower caves to the upper group, about 40 metres above, forming a circular route.
