Shiremark Mill (Ruin)

What you're looking at here are the remains of a medieval watermill, crumbling away in the Surrey countryside a few miles outside Horsham. Stone foundations, fragments of brick, and the occasional glimpse of what might have been a millrace - it's not a dramatic ruin by any stretch, but it tells a proper story if you know where to look.

The site itself is free to visit and sits in open ground, so you can wander round at your own pace. Most people spend twenty minutes poking about, taking photos of the walls, trying to picture how the thing actually worked. It's the kind of place that appeals more to amateur archaeologists and walkers than families expecting a major attraction. Kids might get restless unless they're the type who enjoy a bit of detective work among old stones.

Timing-wise, there's no formal opening hours - it's just there. You'll want to go when the ground isn't waterlogged, which means avoid winter if possible. Summer mornings are best, fewer people about and better light for photographs.

If you're camping at Sands Farm or The Green Escape - both under three miles away - Shiremark makes for a straightforward morning walk before heading back for lunch. Pair it with a proper ramble through the wider Horsham countryside and you've got yourself a decent half-day out. The mill works well as a stop-off rather than a destination in itself, but it's exactly the sort of local quirk that gives a park holiday proper character.
