It was built on the remains of an earlier Anglo Saxon church, possibly belonging to the monastery founded by Abbot Botolph in the year 654.
The nave has 4 original C11 double- splayed windows intact (originally there were 6).
The south doorway was inserted in circa 1200 (now blocked).
The south transept was rebuilt in the late C14
in the C15 the west tower and north porch were added.
