The church dates from circa 1200 and was restored in 1887, the tower restored in 1904. There is a western tower, nave with clerestory and aisles, north chapel, south porch, and chancel.

The western tower is of five stages with battlements and pinnacles, and dates from the 15th century. Like the rest of the church, it is built in ironstone with ashlar dressings. The north arcade is of four bays, the south arcade of five bays, with octagonal piers. The nave roof dates from the 15th century and has human heads and lion mask corbels.

The chancel has a two bay arcade to the north Chapel, and there is a 14th century piscina and three seat sedilia. The chancel also has a 14th century figure of a priest partially sunk into a slab and two more 15th century ledger slabs. There is a 20th century carved wooden reredos.

The south porch dates from 1901.

There are several monuments including a large statue in memory of Richard Welby of Denton Manor. Most of the fittings in the church are 19th century, but the octagonal font dates from the 15th century.

There is a small two manual organ by T. C. Lewis from 1887, and several stained-glass windows in the church including work by Kempe and Ward and Hughes. One window has fragments of mediaeval glass in the tracery.
