The size and architecture of Holy Trinity Church make it unusual for a village parish church, and it was the only church in Suffolk to receive five stars in Simon Jenkins' book "England's Thousand Best Churches". The church dates from the reign of Edward the Confessor; it was then substantially rebuilt between 1467 and 1497 by John Clopton of Kentwell Hall. It is one of the richest "wool churches" in East Anglia and is noted for its flushwork, Clopton chantry chapel and the Lady Chapel at the east end with some surviving medieval stained-glass. Edmund Blunden, the World War I poet, is buried in the churchyard. Next to the church is the Hospital of the Holy and Blessed Trinity, an almshouse founded by William Cordell in 1573 and restored in 1847.
