The Roman town of Caistor St Edmund (Venta Icenorum) lies to the south of Norwich. Particularly good views of the site can be gained from the railway. The site is now managed by the Norfolk Archaeological Trust and there are a series of routes (and interpretation boards) to help visitors to explore the site. The line of the walls are easy to distinguish.
Recent excavations to the south of the walls have shown that occupation continued outside the walls.
