Caldicot Castle

The castle sits right there on the edge of Chepstow, its squat Norman keep rising above flat grassland like something from a child's drawing of the Middle Ages. Caldicot is proper medieval - built in the 11th century by the Normans and then repeatedly rebuilt, extended, and fortified by people who clearly couldn't leave well alone. What you get now is a working fortress that actually feels inhabited in a way many castles don't.

Walking the perimeter walls gives you the real sense of the place. The keep itself is the star - climb the stone stairs inside and you're suddenly looking out across the Severn Vale towards the Forest of Dean. The courtyard is vast, ringed by those thick walls, and there's enough to poke around for a couple of hours without it feeling rushed. Kids will get a kick out of scrambling up towers and peering through arrow slits.

Historically minded visitors will spot the layers - Norman foundations, medieval walls, Tudor additions - though the signage could be clearer about who built what and when. It's the sort of place that rewards wandering more than formal touring.

If you're basing yourself at Penhein Glamping nearby, Caldicot makes an easy half-day out before heading into Chepstow proper. Check opening times before you go - they're seasonal and worth confirming. The grounds are open most of the year, but the castle buildings themselves have variable hours. Worth the drive from anywhere within an hour's radius of Monmouthshire.
