St John's Church, Cockayne Hatley

The first time you round the corner near Sandy and spot St John's Church, Cockayne Hatley, you'll understand why it's worth the detour. This is a proper gem - a small medieval church that somehow feels like you've stumbled into another century entirely. The interior is extraordinarily well-preserved, with original wall paintings dating back to the 15th century that still have real colour and life to them. The chancel is particularly striking, with its decorative schemes largely intact when so many other churches of this age have been stripped back to bare stone.

It's a quiet, contemplative spot rather than a tourist carousel. Church enthusiasts and anyone who appreciates medieval craftsmanship will absolutely rate it. Photographers will find excellent light streaming through the windows, especially in late afternoon. You won't need more than thirty minutes here unless you're deeply into ecclesiastical history, but the quality of what you're looking at punches well above its size.

The setting works brilliantly if you're staying at one of the nearby holiday parks - Cambridgeshire Lakes and Guilden Gate Glamping are both within easy reach. Combining a visit with a walk around the village and a stop in Sandy town centre makes for an unhurried morning or afternoon. Admission appears to be free, though it's worth checking locally before heading out. Winter light does something rather special here, but any season works fine. This is the sort of place that rewards getting slightly lost in country lanes to find.
