We were lucky to find out this place in Viterbo because there was very little information about it and it was closed. But in the moment we were in front of the gate, the guardian arrived for other reasons. He was really nice because he asked us to go with him before we say anything.
He tell us this place was hidden underground and they found it after the World War II. The style of the colonnade is Longobardo. Near to the cloister there was an ancient crypt.
