Rome Underground temples and basilicas

Published on May, 2024

We had a fascinating tour with Paul of the Underground Temples and Proto-Christian Basilicas that culminated at Basilica of San Clemente which is an absolute history lesson of itself. Before arrive at San Clemente, Paul took us on a walking tour to see evidences of ancient Rome hidden all around the city. Small evidences here and there of ancient remnants used even in this day. Paul (an American) is an archeologist but his strength for this tour is his encyclopedic knowledge of ancient history, both secular and religious. He seems to possess a deep faith in the Catholic tradition which allowed us to see the relics and layers of history through his personal faith lens. Just fascinating!! The layers of San Clemente are so revealing. The current church from the 1200s actually has the choir of the 400s church in use today. Below the current church, is the 400s church below which is the 100s Mithraic temple. All of which you can walk amidst as you descend through the layers. Highly recommend!!

Worthwhile beautiful church with impressive historical element
