Basilica di Santa Pudenziana
The St. Pudenziana Church is one of the more ancient churches in Rome, if not the most ancient at all. We have documents indeed that the descendants of the Senator Pudens in 154AD gave the Pope Pius I the Pudens house, because he guested in it the ApostlesPeter and Paul.
According to the tradition, Pudens was a Roman Senator converted to the Christian faith by the Apostles Peter and Paul. The Domus Pudentiana (“the House of Pudens”) became thus a Domus Ecclesia (“a Domestic Church”): the Ecclesia Pudentiana (“the Church of Pudens”). Of this house we have some remains in the excavations at the basement of the actual church. Source: stpudenziana.org
