St Peter

The church sits on a quiet corner near Huntingdon, and it's the kind of place you'll stumble upon while cycling through the Cambridgeshire countryside rather than drive to deliberately. St Peter is a proper medieval parish church, all flint and stone, with the sort of interior that rewards a slow wander - decent medieval glass, a few brasses worth examining, and that particular smell of old wood and stone that never gets old.

It's best suited to history types and anyone already rambling through the area. You're not looking at a two-hour stop here; twenty minutes, maybe thirty if you're genuinely interested in the architecture and monuments. The exterior's the real draw, honestly - that sturdy East Anglian character you get in these smaller churches, weathered and unpretentious.

If you're camped at Grafham Water or St Neots, both within easy reach, St Peter makes a logical break during a day's exploring. The Cambridgeshire fenland around Huntingdon has dozens of these churches, so you could string together a proper ecclesiastical route if you're that way inclined. Just check opening times before you go - country churches keep odd hours and some only open on Sundays. Free to enter, no facilities on site, and best visited when the light's good enough to see what you're looking at inside.
