Archaeologists are set to unearth further secrets of a Roman town on the outskirts of Norwich - and are hoping to discover evidence linking the settlemt to East Anglia's Iceni queen Boudica. Channel 4's Time Team will be filming the excavations at Caistor St Edmund, which are the first within the Roman walls of the site for 75 years. The Roman town of Venta Icenorum lies beneath the fields at the site but historians believe it might have been built on top of a previous Iceni settlement - perhaps even the home of the warrior queen Boudica.
