ScienceDaily (Sep. 24, 2008) — Life has been discovered in the barren depths of Rome’s ancient tombs, proving catacombs are not just a resting place for the dead. The two new species of bacteria found growing on the walls of the Roman tombs may help protect our cultural heritage monuments, according to research published in the September issue of the International Journal of Systematic and Evolutionary Microbiology.
The Catacombs of Saint Callistus are part of a massive graveyard that covers 15 hectares, equivalent to more than 20 football pitches. The underground tombs were built at the end of the 2nd Century AD and were named after Pope Saint Callistus I. More than 30 popes and martyrs are buried in the catacombs.
