Rome's largest catacombs with 26k tombs to open after 7 yrs
Domitilla's Catacombs, which are the largest in Rome as they stretch for over 12 kilometres, will open to the public after seven years of restoration with laser technology. Named after a member of the Roman family, the catacombs house over 26,000 tombs. The frescoes are up to 1,600 years old and depict scenes of saints, martyrs and apostles.
