St. Peter's

The church sits right in Marlow's heart, a proper focal point if you're wandering the High Street. St. Peter's has that solid, confident presence you get from centuries of English parish churches - stone walls, pointed arches, the works. Inside, there's decent stained glass and the kind of quiet that makes you actually notice the light falling through the windows. It won't take more than twenty minutes to look round properly, which is fine because Marlow itself is the real draw here: the riverside walk, the weir, decent pubs and cafes.

Historically minded visitors will appreciate the church's connections to the town's medieval roots, though it's been mucked about with over the centuries like most churches have. Kids won't get much from a solo visit - they'll be bored within ten minutes - but it works well as a stop when you're already exploring the town on foot.

If you're camping nearby - and there's no shortage of options within a couple of miles at places like Hurleyford Farm or Rent Bell Tents - it's absolutely worth popping in on your way to the river. Free entry as far as most churches go. Check the website for opening times before you visit, as they're not always consistent. The real magic is outside: the Thames path, the suspension bridge, the whole Marlow charm that's made it a weekend bolt-hole for Londoners for decades. The church is the anchor point, not the destination.
