Grade I listed.
Dates from the 12th C. onwards, built of Ancaster stone.
Western tower with tall octagonal broach spire with lucarnes, clerestoried nave with north and south aisles and
south porch, chancel and vestry.
North aisle is 14th C. and contains a 14th C. memorial stone with effigy of priest. This stone was removed to the churchyard in the 19th C. and was taken inside again in the 1950's. Traces of medieval painting were found in 19th C. but was lost during restoration!
The south aisle has a recessed tomb with inscription to William Fraunk, died 1385. nearby is a 14th C. piscina.
The font is 15th C. re-cut with flowers.
The nave clerestory is perpendicular with embattled parapets outside, it was added by William Styrlay vicar in 1535, whose brass is in the church. A new chancel was built in 16th C. in the time of Styrlay, originally with north and south chapels.
There is a carved ashlar pulpit, and a set of reused 14th C. poppyhead bench ends.
The chancel was rebuilt in 1853 under S.S.Teulon at a cost of £675. It was built by Anthony Willson whose monument is in the church. The church was much restored in 19th C. and remedial work on the spire was done in 1982.
The organ is by Cousans of Lincoln, 1903.
