Hidden remnants of an Iron Age fort
Tucked between buildings in modern-day Chepstow, the remains of this late Iron Age promontory fort are easy to miss at first glance. But look a little closer and you’ll find the traces of the double-banked and ditched enclosure that encircles this grassy patch of ground. Perched on a cliff edge overlooking the River Wye, you can see why this spot was chosen as the location for a fort by its original builders – and why it was later occupied by Roman invaders.
