A number of local legends surround this mysterious cemetery. Supposedly it contains dirt that had been secretly imported from the site of Jesus' crucifixion. Pisan nobles were determined to be buried with the royal treatment. They also felt comfortable using ancient Roman coffins for their own use, making it necessary to dump out the previous occupants' remains.
The main reason that people would visit this large building, however, is that it contained some beautiful fresco work by Taddeo and others. Almost all of that was destroyed by bombing in the second World War, leaving behind just fragments of what was once a classic relic from the past.
