This church stands out for being built right on top of ancient Roman temples, with columns from those temples still visible in its walls. It’s one of the oldest churches in the city, and you can literally see layers of history stacked on top of each other. The name means “in prison” because it was close to an old jail, adding a mysterious vibe.

  • The walls have real Roman columns sticking out of them—no joke, you can touch history here.
  • There’s a crypt underground where you can see even older ruins and ancient stones.
  • The church is known for its mix of Roman, medieval, and later architecture all in one spot.

  • See Ancient Columns Up Close: The building is famous for having original Roman columns built right into its structure. It’s like a real-life history lesson you can walk through.
  • Explore Underground Ruins: You can go down into the crypt and see remains from even before the church was built. It’s a cool way to see how the city changed over time.
  • Experience a Unique Mix of Architecture: The place is a mashup of different styles and eras, making it super interesting if you like old buildings or want to see something different from the usual.

  • No strict dress code, but it’s a church, so covering shoulders and knees is respectful.
  • Best time to visit is in the morning when it’s quieter and you can explore without crowds.
  • No need to book tickets in advance; entry is usually free.
