Washington, September 25 : A new research has led to the discovery of two new species of bacteria found growing on the walls of ancient Roman tombs, which may help protect cultural heritage monuments.

The tombs in question are the catacombs of Saint Callistus, which 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.

“Bacteria can grow on the walls of these underground tombs and often cause damage,” said Professor Dr Clara Urzi from the University of Messina in Italy.
