Monte San Giorgio is a wooded mountain (1,097 m above sea level) located between the south of canton Ticino in Switzerland and the region of Lombardy in Italy. Monte San Giorgio became a UNESCO World Heritage Sites in 2003, because it "is the single best known record of marine life in the Triassic period, and records important remains of life on land as well." The Italian side of the mountain was added as an extension to the World Heritage Site in 2010.
