The Pula Arena in Croatia is the best preserved Roman amphitheatre in the world. It’s as impressive as the Colosseum in Rome and it retains its complete curcuit of walls.
Today the arena is used for gladiator “fights” and concerts. There has even been a hockey game inside the arena!
When we visited in July there was a film festival in Pula and the arena was one of many venues used for film screenings.
If you get a chance to visit Croatia, be sure to plan for a stop in Pula, it’s a beautiful place.
