St Martin's Church, Brighton

The tower of St Martin's Church rises up from the busy streets of Brighton with a kind of stubborn dignity. Built in the 14th century, it's one of the oldest buildings in the city - which is saying something when you're surrounded by Victorian terraces and modern developments.

What strikes you first is how it sits right there in the middle of everything, completely unbothered by the traffic and the crowds. Inside, the church is surprisingly peaceful. High vaulted ceilings, decent stained glass, and the sort of quiet that makes you actually notice you're breathing. The medieval bones of the place are obvious if you know where to look - thick stone walls, Gothic windows, evidence of centuries of tinkering and repair.

This works best for architecture types and anyone interested in actual medieval Sussex, rather than the seaside postcard version of Brighton. If you've got kids, they might last twenty minutes before getting restless - it's not interactive or dramatic. But if you're the sort who likes to potter around old churches and read plaques, you could easily spend an hour in here.

It's free to look round, though opening hours can be a bit variable depending on services and volunteer availability. Worth checking ahead if you're planning a specific visit. The nearby Southdown Way and Blackberry Wood caravan parks are both within easy striking distance - proper bases for exploring the area. St Martin's makes a good quiet counterpoint to Brighton's seafront chaos.
