Mount Amiata (Height: 1,738 m) is a mountain chain of volcanic origin that rises between the valleys of the Orcia, Fiora, and Paglia rivers. The volcano is considered extinct as the last activity dates to approximately 200-300,000 years ago. Amiata has always been the object of research and the extraction of cinnabar, the sulfide from which mercury is obtained. In fact, in the municipality of Abbadia San Salvatore, one may visit the Mining Museum Park. On the top of Mount Amiata there is a large monumental cross, commissioned by Pope Leo XIII who proposed to place 20 crosses on the tops of various Italian mountains to celebrate the holy year of 1900. The cross on Mount Amiata was the ninth built in chronological order (1910). The cross was restored and illuminated on the anniversary of its hundred-year anniversary in 2010.
