Saint Botolph

The tower of Saint Botolph rises above the Lincolnshire flatlands like a stone exclamation mark, visible for miles across the surrounding countryside. This is Boston's most famous landmark - a 14th-century church that dominates the skyline and tells the story of a town that was once as wealthy and important as London itself.

The church itself is massive inside, all soaring arches and stained glass, with the kind of scale that makes you understand just how much money flowed through Boston's medieval wool and grain trade. The lantern tower at the top is the real draw - if you're up for 365 steps, the views across the Fens are genuinely spectacular, stretching all the way to the Wash. On a clear day you can see for twenty miles.

It's free to wander around inside, though climbing the tower will cost you a few quid. You'll need a good hour if you're doing the full ascent, less if you're just having a look at the interior. The steps are tight and steep - not a push for anyone with mobility issues, and honestly, small children might lose interest before halfway up.

History enthusiasts will find plenty to occupy them. This is where the Pilgrim Fathers worshipped before heading to America. There's real substance here, not just a pretty building. Families staying at Lakeside Touring Caravan Park or Camper UK Leisure Park nearby could easily pop into Boston town centre and spend an afternoon poking around the church and the medieval marketplace. Worth the detour, especially if you're doing a broader tour of the Fens.
