The Church of St Aldhelm, formerly the parish church of Belchalwell, is in the southwestern part of the parish. The nave has late-12th-century origins, though only part of the south wall remains from this date. The south doorway is well preserved, dating to about 1190, and is ornamented with chevron and dog-tooth patterning. The north aisle, chancel, south tower and south porch are 15th-century additions, though at the end of the 19th century the east wall of the chancel and all the north aisle were largely rebuilt, as were the west walls of the nave and south porch.
