Romans in Chester, Chester
If you chance it right, you might run into a real-life Roman at the ruins! Well, maybe not, but you'll find an Englishman dressed as a gladiator explaning Roman culture to a pack of schoolkids. Chester's ruins are a popular field trip destination, and why not? When I was a kid, we went to Memphis (Tennessee) for a field trip and despite local propoganda, that town was not founded by ancient Egyptians. So, go to Chester and talk to a Gladiator!
The remains of the largest stone built Roman amphitheatre in Britain you will find next to Newgate. In Roman times there was space for 8000 spectators here.
There's a little park next to the city wall. There's remains of Roman columns here as well as a Roman heating system. It as one of my favourite parts of Chester actually.
Several Roman column bases and masonry from Roman colonnade and underground heating system have been put on display in this small park.
The foundations survive from the Roman tower which stood just inside the south-eastern corner of the legionary fortress. At the top of it there was probably a rock-hurling balista.
