Middleton Stoney Castle

What's left of Middleton Stoney Castle is honestly quite modest - think earthworks and overgrown foundations rather than towering battlements. The motte-and-bailey structure sits just outside Bicester, and if you're into Norman fortifications, it's worth a quick detour to understand how these early castles worked, but you won't be spending hours here.

The site itself is free to visit and accessible as a sort of open space, though there's no visitor infrastructure or interpretation boards to speak of. You'll need to do a bit of detective work with a map to find it properly, which adds to the sense of discovery if you're the type who enjoys that sort of thing. The actual walking about takes twenty minutes, maybe half an hour if you're photographing every angle.

It suits local history enthusiasts or anyone with a serious interest in medieval military architecture. Family groups will likely find it underwhelming unless the kids are genuinely fascinated by earthwork structures. If you're camping nearby at Weston Caravan and Campsite, Greenhill Leisure Park, or Diamond Caravan Park, it's close enough for a morning outing without feeling like a proper destination in itself.

Combine it with Bicester town or a walk along the Cherwell if you want a fuller day. On its own, the castle is a bit too sparse to justify planning your whole trip around, but as part of a broader Oxfordshire exploration it serves a purpose.
