Grade II*listed
The church dates from the 12th century onwards and was restored by Fowler in the late 19th century.
There is a large west tower, nave and chancel in one, and north vestry.
The church is entered by the west doorway of the tower which dates from the late 12th century.
The tower is of three stages with six large buttresses. It is some 16'3" square internally. Large size is an indication that the population at the time was greater. There is a large arch into the nave.
The tower was enlarged in the late 14th century and there are battlements with pinnacles and gargoyles.
There are three bells.
By the late 18th-century the church was too big for the inhabitants of the parish and was in very poor condition. It was therefore rebuilt, except for the tower.
In 1870 the nave and chancel were converted into one by James Fowler. The north vestry was added. Therefore the majority of the church except for the tower is from the 19th century, including the font.
The reredos is by A. B. Skipworth and Conrad Dressler.
The organ was originally built by Benjamin Flight and was purchased in 1935 from the Wesleyan Chapel in Kirton in Lindsey. It has recently been restored.
