It's over 2500 years old. The prison itself is very interesting. The tour guide woman and colorful electric lights to "liven up" the intro is way over done. So, ignore all that leads up to actually going down into the prison, which is like a cistern.
This cell once held St. Peter and St. Paul.
Water is continually dripping here. The commentary that goes along with the tour says something of the effect, that this water connects us with the past. Peter and Paul heard this same water dripping while they were here in captivity.
See the column where Peter was chained. It is said that a miraculous fountain sprung up here so that he could baptize his jailers. (Acts 16)
The hole where prisoners were lowered into the cell.
After viewing the cell, the tour goes into St. Joseph's chapel where all the tourists sit and listen in their headphones in their own languages (English, Italian, Spanish, German, etc.) to a very clear presentation of the Gospel. They emphasize the love of God that covers over a multitude of sins. Gana and I were so moved and impressed with the consistent testimony of Jesus right over the place where early Christians were imprisoned for their faith. Redemption.
