Toga Town - Caerwent, Monmouthshire, South Wales

Caerwent in South Wales is Britain's best-preserved Roman town; but there are still unexplored pockets. Neil wants to find some Roman retail outlets, but Mick is more interested in medieval remains. Louise Revell describes existing features, including the basilica and the central forum where political debates would have taken place. Geophysics suggests a full-scale Roman villa on the site. The diggers are uncovering a maze of walls, which are hard to understand. From a second century handbook, Louise gives Phil and Matt some tips about Roman oratory. Meanwhile Stewart is playing with a groma, a Roman surveying tool. At the finale Phil and Matt engage in a debate, kitted out in their togas. Finds include a 3rd century coin, a tool for removing earwax, a twisted wire bracelet, and a folding penknife handle decorated with gladiators. They are also joined by Roman archaeologist Peter Guest.
