Hi!
Thank you to review your experience.
The Baths of Caracalla was built on 216 after Christ. What you can visit now is an extended archeological area and impressive for most of turists visiting Rome.
Next time you can think to take a guided tour. A guide can help you a lot on understanding how facinating this area was!
I hope, by the way, you appreciated our job.
See you soon in your future trip in Rome!
