The present church, of which the abbey and prior were the patrons, was dedicated to the same saints as the abbey, and was erected in the Geometrical style of architecture of a severe character, considering the date it was built—for at that time that style of architecture was dying out, and was not so severe in its character—but in this district, styles of architecture did not give place to the new till much later than elsewhere in England and on the Continent. The dimensions of this early church are easily defined in the present building externally by the original buttresses on the west end of the nave, the north and south ends of the transepts, the south-east buttresses of the nave, and the south wall of the chancel, which had been built upon the earlier chapel foundations as previously mentioned, and the angle buttresses at the east end of the chancel; and visitors should notice that in building on the old foundations, the east wall of the chancel is not at right angles to the two other walls of the building—the northern wall is upwards of two feet longer than that on the southern side. Such was the early church at Spalding, with probably a campanile or small tower at the west end of the north aisle. At the restoration in 1866 the foundations at that corner of the building were on examination found to be more solid and capable of bearing a much greater weight than the rest of the building. That a campanile or tower formed part of the early church—and in the Early English style of architecture—is confirmed by the fact that Early English base mouldings and windows are worked into the present tower, as well as ledger stones of Perpendicular date and some whole stone coffins. In relation to this tower it is interesting to record that in 1401 there was another dispute between the townsmen and the prior in relation to the bells, and it was probably in consequence of that dispute the present tower was erected and the bells hung in the same. During the Curvilinear Period the south aisle, the south outer aisle, and the present tower were added, with Thomas à Becket’s Chapel at the east end of the south outer aisle. This chapel was used for a great number of years as the Grammar School. This Curvilinear tower was not originally intended to carry a spire, but one was at a subsequent period added, which so severely tried the strength of the tower that at the time of the Restoration it was in so dangerous a condition that the bells could not be rung. In the Rectilinear Period the church was further enlarged, and the following were added:— The present North Aisle. Outer North Aisle. North Porch. One Buttress on the South Outer Aisle. Two Buttresses on south side of Chancel. South Porch. North-east Buttress of North Transept. Stairs to Rood-loft.
