St Mary's dates from the 12th century onwards, and has a nave with north and south aisles, a western tower, a chancel with south Chapel, and a south porch with parvis.

The north arcade dates from the mid to late 12th century, and is of five bays plus a taller, later eastern arch.

The piers are circular and the round arches have zigzag decoration.

The south arcade is of four bays and dates from circa 1300. It has octagonal columns similar to those in Lincoln Cathedral, topped with water leaf capitals. Both the aisles were later enlarged.

The tower dates from the 13th century, and has decorated parapets with eight pinnacles from a later date. There was initially a spire on top. The tower arch has stiff leaf capitals and keeled shafts.

The south porch has a reset early 13th century archway, and an upper chamber with a door high in the nave, once reached by a stairway.

In the 14th century the south chapel was built with a three bay arcade towards the chancel. The capitals contain a number of green men, many of its windows are reused In the 15th century a clerestory was added to the nave.

The east window of the chancel was reduced in height when the gabled roof was lowered.

There is a brass from the 15th century in the chancel floor and the remains of a 17th-century monument with only a black marble column still standing.

There is a three manual organ by Forster and Andrews.
