The Catacombs of Domitilla in Rome extend over twelve kilometers on four levels underground, and are full of decorations and frescoes that tell stories about Christian communities from the early centuries of the first millennium. After three years of restoration – using cutting-edge laser technology to preserve the ancient frescoes – this archaeological treasure has recently reopened to the public.

Once again visitors can admire masterpieces of Paleochristian art – including some representing activities by the ‘praefectus annonae’, the Roman imperial office in charge of distributing wheat.
