Except for its Colossus it has NOTHING interesting.
We went there for a one-day fieldtrip last year and were bored to tears.
The plan was to be there for 7 hours, but after the third hour we saw everything interesting and therefore we had 4 hours of utter boredom.

It’s fun to see the Roman Colossus, but man, don’t plan staying there for a longer period of time…
