When it was built in the 14C, St Botolph's was the tallest church in England; from its 83 m Flemish-style tower, known as the Boston Stump, visitors can see as far as Hunstanton (64 km east) and Lincoln (50 km northwest) on a clear day. The building possesses a rare unity of architectural style, with a Decorated nave and a Perpendicular tower and octagonal lantern. Inside, note the 14C misericords.
