St Peter's Church, Carmarthen

The tower of St Peter's rises above Carmarthen's town centre with all the gravitas you'd expect from a church that's stood here since medieval times. It's genuinely striking - that red sandstone catches the light properly, especially on a clear afternoon when you're walking up from the high street.

Inside, the place has real presence. The nave feels proportionate rather than grand, which suits a working parish church. There's decent medieval stonework to spot if you're into that sort of thing, and the kind of accumulated history you get in churches that have been used continuously for centuries - nothing artificially preserved, just worn and lived-in.

This works best for two types of visitors: architecture enthusiasts who'll spend a good twenty minutes picking over the details, and anyone doing the walking tour of Carmarthen town itself, where it's basically unmissable. Kids won't linger unless they're already into old churches. It's free to wander in during opening hours, which aren't widely advertised - best to check locally or call ahead.

If you're staying at one of the nearby farms - Church House, Quarry Lodge, or any of the others within a few miles - this is a worthwhile twenty-minute detour when you're in town for supplies or a proper meal. Pair it with wandering the medieval streets and the castle ruins nearby, and you've got a decent morning. Don't expect to spend hours here, but it's the sort of place that rewards a proper look.
