National Trust - Buckingham Chantry Chapel

The chapel sits right in the heart of Buckingham town centre, a real survivor from the 15th century that most people walk past without noticing. It's tiny - genuinely small - but that's rather the point. Built as a chantry chapel where priests would say masses for the dead, it's one of only a handful still standing in England in anything close to original condition.

Inside, you'll find modest medieval stonework, a bit of stained glass, and the sort of peaceful quietness you don't get in bigger churches. The National Trust maintains it, though opening hours can be irregular - worth checking before you go. Admission is free, and you won't need more than thirty minutes here unless you're really into 15th-century ecclesiastical architecture.

It's the sort of place that appeals most to local history enthusiasts and anyone doing a proper walking tour of Buckingham itself. Families with young kids might find it underwhelming unless they're already interested in medieval buildings. The town around it is pleasant enough for a wander, with decent pubs and cafes.

If you're camping at Hedgehog Retreat or one of the other sites nearby - Silverstone Woodlands and Barton Hill Farm are both within five miles - this makes a sensible rainy-day stop or a quick morning visit before heading elsewhere in Buckinghamshire. It won't dominate your itinerary, but it's worth knowing about if you're spending time in the area.
