St Denys (Colmworth Parish Church)

The tower of St Denys rises unexpectedly from flat Cambridgeshire countryside near Colmworth, a proper medieval structure that stops you dead when you round the bend. This is Perpendicular Gothic at its finest - all soaring windows and buttresses - built when the wool trade was pouring money into East Anglia. Inside, the church is surprisingly spacious and light, with a nave that extends further than you'd expect given the village's modest size now.

Walkers and architecture enthusiasts will get the most from a visit. The churchyard itself is peaceful, with old graves scattered among yews, and you'll likely have the place to yourself on a weekday afternoon. Allow twenty minutes for a proper look around, longer if you're the type to read every brass and examine the roof timbers.

Admission appears to be free, though opening times aren't posted anywhere obvious - best to check locally before making the trip. It's an easy detour from St Neots, the nearest proper town, and works well as part of a countryside ramble rather than a destination in itself.

The flat terrain around here suits caravanning brilliantly. St Neots Camping and Caravanning Club Site is less than five miles away, well-placed for exploring the Cambridgeshire churches circuit. If you're after a quiet morning walk with medieval stonework thrown in, St Denys delivers. Not dramatic, but genuinely worth the diversion.
