St Giles' Church, Northampton

The soaring spire of St Giles' is Northampton's most recognisable landmark, visible for miles across the town centre. This is proper medieval architecture - built in the 14th century and rebuilt after a devastating fire in 1675 that nearly wiped out the entire town. Step inside and you're looking at one of the finest parish churches in the country. The interior's surprisingly spacious, with a striking wooden roof and some genuinely moving monuments. There's a real sense of continuity here - centuries of Northamptonians have worshipped in this exact spot.

It's worth going for the architecture alone, but history buffs will be genuinely gripped. You'll spot memorials to local worthies, Victorian additions that show how the town evolved, and details that reveal how Northampton's built itself back from that catastrophic fire. The church sits right in the heart of town, so it's easily combined with a wander through the town centre or lunch nearby.

Unlike many churches, this one feels actively used rather than museumified. Pop in on a quiet morning if you want proper time to look around without feeling rushed. If you're staying at Sywell Country Park just five miles out, St Giles' makes a solid half-hour detour on the way into town. It won't keep you occupied for hours, but it's absolutely worth the walk up from the town square. The view from outside, particularly of that spire against a clear sky, never gets old.
