The nave, which is three bays in length, is undoubtedly the oldest part, and the point at which it originally terminated is clearly shown by the diagonal projection of the angle buttress which still remains. The chancel appears to have superseded an older foundation of smaller dimensions. It is of equal width with the nave, and, in fact, a continuation of it, and both are covered in with a timber roof of obtuse pitch, with elaborately moulded and ornamented beams and rafters. The external walls of both the nave and chancel are surmounted by an embattled parapet, relieved at intervals with crocketted pinnacles, that are carried above the edge of the parapet wall as a termination to each buttress. There being no clerestory or side aisles, the windows are unusually lofty. They are of pointed character, with traceried heads and mouldings, terminating in curiously-carved corbels, that have afforded scope for the humorous fancy of the mediæval masons. On the south side is an open porch with stone seats, that has at some time or other been added to the original structure, as evidenced by the fact that the greater portion of the buttress has been cut away where it is joined up to the main wall. It has coupled lights on each side, with hood mouldings, the one on the west terminating in a curiously-carved corbel, representing a rose with two heads enclosed in the petals, an evidence that this part of the fabric must have been built shortly after the union of the rival houses of York and Lancaster, in the persons of Henry VII. and Elizabeth the eldest daughter of Edward IV. The tower is well proportioned, and, rising gracefully as it does above the surrounding foliage, forms a conspicuous object for miles around. It is remarkable for the armorial shields, 14 in number, carved in relief, in stone, on each face. These insignia are especially interesting to the antiquary and the genealogist, as showing the alliances of the earlier lords of Gawsworth. They include the coats of Fitton, Orreby, Bechton, Mainwaring, Wever, Egerton, Grosvenor, and Davenport, as well as those of Fitton of Bollin, and Fitton of Pownall, and there is one also containing the arms of Randle Blundeville, Earl of Chester, with whom the Fittons appear to have been connected.
