The nave and chancel may be from a possibly late C10 minster church, with a north aisle of c1170.  The tower is C13 with a C15 upper stage.

The farm opposite the church is on the site of a small Benedictine nunnery, called Nonneminstre in Domesday Book (11, 59), which was a daughter of the Norman house of Almanêches and may have been pre-Conquest in origin (Barr-Hamilton p39).  As an alien house, it was suppressed in the early C15.  Like others of its kind, it took over the chancel of the existing parish church, which may previously have been the minster known to have been here. 

The walls of the tall nave and much of the chancel are 2ft 7in thick (Taylor and Taylor p410) and over the north arcade is the head of an early window.  Like the head of a round-headed south doorway with through-stones above the C12 one, this work could be C10.  The south east quoins of the chancel look contemporary.  Its exceptional length for the period could equally be explained by its use by the nuns or by the minster.  The tall chancel arch has a round head of large stones and is also early, though probably altered.  Each jamb has two plain abaci, one at the springing of the head and the other, thicker and renewed, about two-thirds of the way up.  The lower ones are level with the abaci of the north arcade and Ian Nairn suggests (BE p267) they were an attempt to correct the proportions, though they could have been for a rood or, as the Taylors proposed, have belonged to a screen. 

The earlier C12 west doorway has become the tower arch, with a segmental rere-arch and, on the tower side, two orders and plain abaci.  When built, it was the main entrance, though the lower, chamfered south doorway is of the same date.  The chancel had two doorways; a north one may have opened into a chapel longer than the present vestry and a now vanished round-headed south west one (Fisher p148) was probably for the nuns.

The strikingly low north aisle was added between c1170 and 1200.  Views on the precise date vary, depending on the interpretation of the detail.  P M Johnston saw the four-bay arcade as evidence for the earlier date (1 p208), though the best such evidence is the head of the blocked round-headed west window above the present C19 one (blocked and visible inside).  The arcade has pointed, unchamfered arches, square responds, narrow abaci and round piers with square bases and capitals.  Two of these are scalloped and the easternmost has volutes, which have been cited in support of a dating as late as the early C13 (www.crsbi.ac.uk retrieved on 8/4/2013).  On balance, the arcade is probably the more reliable indicator.  At its east end, a rounded arch with a depressed head led originally into the chapel and now into the vestry.  It is altered, but could date from any time in the later C12.  When the aisle was added, the nave was heightened by 5ft, accentuating its proportions.  Probably soon afterwards, the lower stage of a tower was started.  Unusually, it has pointed north and south doorways (the south one now leads into an extension - see below) and there are lancets above, the west one blocked.  The final alterations in the early C13 comprised the insertion of lancets.  The small north one of the chancel, which is substantially original, has a concentric rere-arch and thus predates the long south ones in the nave and chancel, though these are mostly renewed.  High to the south is a round, cusped window, more like a clerestory, which is perhaps a little later in date. 

Discoloration on the west doorway and arcade suggests fire damage, probably in the early C15.  The aisle roof built afterwards seeks to overcome the problems inherent in a roof that comes within seven feet of the ground, notably a tendency to slide.  To counter this, it has separate kingposts on ties, which are supported on vertical posts with struts, the inner ones placed inconspicuously behind the piers of the arcade.  The nave roof of the same date has braced crownposts and there is a flint and timber north porch with cusped bargeboards.  Though the chancel seems to have escaped the fire, its roof is also C15 with alternating arch-braces and crownposts on moulded tiebeams.  In addition, a segment-headed east window with three lights of panelled tracery was inserted and reset in the vestry is a two-light square-headed one from the south nave (1 p212).  Finally, the top stage of the tower was completed or rebuilt with square-headed bell-openings (renewed) and battlements.  The C15 flintwork is more regular. 

The north doorway looks C16 and the north chapel had gone by the late C18 (VCH 5(2) p232) – Nibbs (1851) shows the chancel wall this side was blank.  In 1804 the Sharpe Collection drawing shows the aisle with only post-Reformation dormers for a gallery, but by 1850 there were round-headed windows (Adelaide Tracy II p67).  There had been work on the chancel in the 1830s (VCH ibid), including a new south window.  In 1864 G Truefitt (B 22 p957) restored the nave and aisle, including the present lancets.  Those in the aisle have rere-arches of exposed flint.  His work was fairly light, for it cost only £648 8s 0d (PP 125) in all.  G M Hills restored the chancel again in 1883-84 (B 46 p80), also in a modest way, as the cost of £640 (KD 1899) shows.  He rebuilt the nave gable higher, re-using the C15 roof, and added a vestry and organ chamber on the site of the north chapel.  In 1902 P M Johnston repaired the tower to commemorate the Coronation of Edward VII (1 p214) and his article on the church was published the next year.  He replaced the battlements and bell-openings, which had lost their mullions and cusping, and revealed the south doorway.  In 1933 he did more work on the roof and to an unspecified buttress (CDG Feb 1933 p73).  In 1949-50 there were further repairs by S Roth (ICBS).

More recently, a small extension, more the size of a vestry, has been added on the south side of the tower, where it is inconspicuous.  Unusually, it is apsidal in form.
