The nave has the medieval core
A medieval church virtually rebuilt in 1767 https://historicengland.org.uk/listing/the-list/list-entry/1352321?section=official-list-entry
The nave walls are of stuccoed masonry with medieval freestone quoins, apart from the east wall which, like the chancel, was rebuilt 1767 with quoins of gault brick.
4 plain Y-traceried windows and 2 lancets, all of freestone in the manner of early C14, but perhaps C18 renewals.
The butt- purlin nave roof is probably of 1646.
Complete box pews, with a matching triple- decker pulpit.
Good mid C14 octagonal limestone font
Inside the church of King Charles the Martyr, built in 1767. The barrel organ, installed in 1820, is the only one remaining in Suffolk. There are Easter flowers before the 18th-century octagonal font, with its classical cover and "big, coarse leaf" decoration noted by Pevsner.

the bowl has carved foliate patterns and shields, and the stem a moulded capital and base.
In the chancel are 6 marble floor slabs to C17 members of the Cropley family, and another is in the nave.
