Rome is a treasure trove of monuments and invaluable works of art and now with these new excavations made under the Church of San Giuseppe dei Falegnami where there once a famous prison called Mamertine (here was incarcerated Saint Peter) there is a new, fascinating addition to Rome’s ancient heritage.
Probably the site will open to the public on 1 July; the Vicariato is planning to put it on the list of the Christian places one should visit while in Rome.
