Sited along the Appian way, these catacombs were built after 150 AD, with some private Christian [[hypogeum|hypogea]] and a funereal area directly dependent on the [[Catholic Church]]. It takes its name from the deacon [[Saint Callixtus]], appointed by [[Pope Zephyrinus]] to administer this cemetery. On Callixtus' accession as pope, he enlarged the complex, that quite soon became the official one for the Roman Church. The arcades, where more than fifty martyrs and sixteen popes were buried, form part of a cemetery complex that occupies fifteen hectares. The Catacombs of San Callisto are around 90 acres large, 12 miles long and contain four levels, extending to a depth of more than 20 meters underground. Because of the large number of popes buried inside the catacombs, it has on occasion been called the "Little Vatican".
