Wisbech Castle

The remains of a Norman motte-and-bailey castle sit quietly in the middle of Wisbech, easy to walk past if you're not paying attention. What you actually get is a grassy mound with the ruins of a keep on top - not the dramatic medieval fortress you might be imagining, but rather a chance to clamber about and get a proper sense of how these early defensive structures worked. The museum itself is modest, housed partly in the castle buildings, covering local history and the town's significance as a medieval port. It's worth an hour if you're passing through, less if you're short on time.

Families with young kids will find the mound itself entertaining enough - there's something about climbing artificial hills that keeps them occupied. Walkers and history buffs will appreciate the quietness of the place and the way it reveals how Wisbech was once a serious settlement before the fens were drained. Not a destination in itself, but a sensible stop if you're based at one of the nearby glamping spots - Glamping with Llamas is barely two miles away, and Westerby Farm only marginally further. Both offer proper bases for exploring the Fenland landscape.

The castle gets quiet outside school holidays and summer weekends, which is when it's most worth visiting. Check ahead for opening hours and admission - details are sparse online, but locals in Wisbech town centre will point you in the right direction. Allow a couple of hours if you're combining it with a walk around town.
