From the Internets, I learned that "Hadleigh is one of those pleasant, if rather self-important, Suffolk towns, whose remoteness from other places of any size makes it a microcosm of bigger towns - the factories, shops and housing estates all to scale. ... If Hadleigh is small, however, St Mary is not. This is one of the grand Suffolk churches, the only big one with a medieval spire; indeed, the only proper wood and lead spire in the county. It was built in the 14th century, and the exterior bell, a 1280 clock bell doubling as a sanctus bell, is Suffolk's oldest. It is one of the longest churches in Suffolk. The Catholics who built it are now banished to the suburbs, and the surprising modern church of St Joseph."
