Tours > Wales > Southeast Wales The Southeast: Gwent and the Borderlands This is a border region in which the Romans and later the Normans made their presence felt most strongly. The gentle scenery of the Wye Valley and the fertile lands that stretch down to the Severn Estuary shelter a Roman amphitheatre, baths and barracks, ruined abbeys, impressive medieval fortifications, and delightful manor houses in which one can relive the days of the period of the Civil Wars.
