A major portion of ancient Rome lies in deep slumber about 9 and 15 meters underground. With less scope of excavation in the deeper sections we have to rely on the catacombs, scavi, and crypts on religious sites to decipher the life in classical times. The famous Catacombs of Rome are the ancient burial places which are made of underground passages. The original Roman custom was cremation, after which the burnt remains were kept in a pot. But around the 2nd century AD, burial of unbound was being practiced. Christians also preferred burials. Wall graves were dug and were usually laid out vertically as it could contain one or more bodies. Another way was to have burial rooms containing graves all for one family. It gives you a chill when you descend into the realm of those dead and still dwelling here. Capuchin Crypt behind Piazza Barberini is where you can see the bones of thousand Capuchin monks. You’ll find skeletal remains of 3,700 bodies believed to be Capuchin friars buried by their order. There are six total rooms in the crypt. These would be the spooky highlights of your tour. The interesting history of the Basilica of Saint Clement makes it a key point to visit. Travel Trip- The Catacombs of St. Callixtus are closed on Wednesdays.
