Watch sunrise through the rock window
UNECO World Heritage Sardona
Few places illustrate the history of the Alps as impressively as the UNESCO World Heritage Site between the Murgsee lake, Pizol and Martin’s Hole near Elm.
The seldom line along the rock face around the Piz Sardona marks the Glarus overthrust – a phenomenon of world interest. Here, older rock strata have edged their way above younger rocks.
Martin’s Hole near Elm is a 22×19 meter wide rock window. There are two days in the spring and the summer in Elm when sunrise the sun shines through the Martin’s Hole directly onto the Church of Elm. Even astronomers are fond of making a pilgrimage to Elm on March 12 and 13, and on September 30 and October 1. The moon too is visible in the Martin’s Hole at certain intervals.
