St Peter's Church, Glentham

The church sits quietly in the village of Glentham, about four miles south of Market Rasen, and the moment you push open the heavy wooden door you're hit with that particular smell of old stone and centuries. St Peter's is a proper medieval parish church - the sort of place where you can actually feel the weight of time without it being theatrical about it.

Inside, the nave is straightforward and honest. There's good 15th-century work here, and if you care about these things - and you should - the architecture tells you something real about how people in this corner of Lincolnshire lived and worshipped. The windows have that yellowed quality that only very old glass gets. You can spend a proper hour picking through the details, or dash round in ten minutes if you're just ticking boxes.

This works best for walkers and history types rather than families with restless kids, though a quiet child will find the old graveyards atmospheric. There's no gift shop or café nonsense, which feels right. Free to visit, as most parish churches are.

If you're staying at Lincolnshire Lanes Camp just down the road, this makes an easy ramble - take the footpaths between Glentham and Market Rasen if the weather's decent. Don't expect drama or crowds. What you get is genuine, unvarnished medieval England, which is precisely what makes it worth the visit.
