The Mines of Paris (in French Carrières de Paris — "quarries of Paris") are made up of a number of abandoned, underground mines under Paris, France, connected together by large chambers called galleries. Three main networks exist; the largest, called the "grand réseau sud" ("large south network"), lies under the Ve, VIe, XIVe and XVe arrondissements, a second under the XIIIe arrondissement, and a third under the XVIe, though other minor networks are found under the XIIe, XIVe and XVIe for instance. Together, the mines and galleries run for about 280 kilometres.
