Life was hard for a Roman legionary in first-century Wales. When he wasn’t cooped up in his barracks or being barked at by a centurion he was out risking his life in skirmishes with ancient Britons.  But here in Isca, one of just three permanent legionary fortresses in Britain, there were compensations. He could always hang out with his friends at the fortress baths – or take a stroll to the amphitheatre to watch the gladiators.
