The church appears to have consisted at first of a chancel, nave with north and south aisles, western tower with the aisles prolonged on either side of it, and western porch. The only subsequent additions were, in the fourteenth century, a small vestry on the north side of the east bay of the chancel, and in the sixteenth century the Wilshyre chantry, in the space between the vestry and the east wall of the north aisle. In the fourteenth century (probably during the bishopric of Haymo de Hethe) the windows at the west end of the nave and aisles, and that in the west bay of the south wall, were inserted; and at the same time the tower-piers were altered. Probably they were, like the other piers throughout the church, exceedingly delicate, and were thought to be not sufficiently solid to carry the weight of the steeple; but at any rate it is clear that the piers, with their capitals, are not earlier than _circa_ A.D. 1350, whilst the arches have earlier mouldings, and are of the same character as the rest of the church. It was at the same time that additional support was given to the eastern piers of the tower, by the addition of bold flying buttresses, spanning the aisles, and visible only on the inside of the church. The staircase to the tower, placed against the south-west angle, appears to me to have been added at the same time; whilst the upper part of the tower retains nothing but poor fifteenth-century work, and was probably entirely rebuilt at that time, if, indeed, it is not a work of the seventeenth century, undertaken after the fire which melted the bells, in A.D. 1638.
