A mere 7.2 km from the very active volcano Mount Etna, Sicily; in the small town of Sant’Alfio at Piazzale Castagno dei Cento Cavalli, you will find the oldest chestnut tree in the world estimated as being between 2000 and 4000 years old with a girth of 57.91 meters. Legend has it that Princess Giovanna of Aragon and a hundred horseman sought shelter under the tree in a violent thunderstorm.
