Uffington Castle

Built around 2,500 years ago, it covers eight acres and once served as a substantial defended settlement. You can still walk the perimeter and trace the impressive earth banks and ditches that protected it, with the western entrance gate remaining clearly visible. The eastern entrance was deliberately sealed long after construction, which tells you something about how defensive strategies evolved over time.

What sets this place apart is how directly you can engage with Iron Age history without the heavy-handed visitor infrastructure that can dominate other archaeological sites. Walking around the ramparts gives you real insight into the engineering effort required to build them. The views themselves justify a visit, stretching far across the landscape on clear days. From certain points around the fort, you can also spot the White Horse of Uffington, the famous chalk figure carved into the nearby hillside.

Wantage lies about five miles south if you need shops or services. The site is completely free to visit, making it excellent value as part of a Cotswolds trip. Spring and autumn work particularly well, when the grass is green but won't be so overgrown that walking becomes uncomfortable.
