We were headed for a different fort, however - the iron age hill fort that tops the wooded ridge overlooking the village.

The Silures - a fierce tribe, apparently - fought back against the Roman occupation, but were eventually either beaten or persuaded to work with them.
When the Romans left in 400AD, many hillforts were reoccupied. During this period, King Arthur is said to have led the fightback against the Saxon invasion. In the 12th century, Geoffrey of Monmouth claims Caerleon is the site of Camelot.
