Summary Authors Fabio Di Stefano; Stu Witmer

Seen above, the Sun sets directly behind the natural arch of Mount Forato in the Alpi Apuani UNESCO Global Geopark of Tuscany (Italy). The arch is one of the largest in Italy and is known locally as the Pania forata (perforated hill). It was probably formed by the wind and water erosion of the carbonate rock. The Apuan Alps originated in the Paleozoic Era (about 500 million years ago) and are known for their combination of marble mountains and karst caves. Sometimes it's possible to see planets or the Moon through the arch. Photo taken November 10, 2020.
