In the seventeenth century the east end was used as a church and the west end as a school. In 1760 the Parish of Tynningham was added to Whitekirk, and some of the fittings of the former were brought to the latter. Thus the Haddington gallery in the north transept was adorned with the front of the gallery from Tynningham. During this century some attempts have been made to improve the structure. In 1832 a “pseudo south transept” was built, and the Seacliffe gallery (which resembles a large Dutch cabinet) was introduced. This church, like many others erected in the fifteenth century, is on [Illustration: FIG. 1187.--St. Mary’s, Whitekirk. Plan.] the plan of a cross without aisles (Fig. 1187). The choir is vaulted with a pointed barrel vault, and the outer roof is slated. Over the crossing (Fig. 1188) rises a square tower, finished with a plain parapet. The east [Illustration: FIG. 1188.--St. Mary’s, Whitekirk. View from South-West.] end is square, and there is a fine entrance porch at the south-west angle. The church is built with red freestone, which is toned with age, and the whole building is one of the most picturesque and pleasing of our old parish churches. The nave and choir measure internally 103 feet in length by about 22 feet in width. The choir is divided by bold buttresses into two bays, [Illustration: FIG. 1189.--St. Mary’s, Whitekirk. Buttress and Window in Choir.] in each of which is a traceried window, the cusping of which is peculiar. The forms of the buttresses and tracery are shown in Fig. 1189. The east end has a small circular quatrefoiled window set high in the wall (Fig. 1190), over which is a panel containing a shield bearing a fessé with a crozier behind it, probably the arms of Abbot Crawford of Holyrood (1460-1483). The west end (Fig. 1191) and the south transept have been rebuilt. The south-west porch (Fig. 1192) is one of the most striking features [Illustration: FIG. 1190.--St. Mary’s, Whitekirk. East Gable.] of the structure. It measures 13 feet wide by 9 feet deep internally, and has a stone bench on each side. The entrance is by an open archway, with clustered shafts, having enriched caps from which spring the bold mouldings of the arch. At each of the outer angles of the porch is a diagonal buttress having a niche on the inner face, and finished on the top with crocketed pinnacles. Over the doorway there is a panel with small buttresses at the jambs, and canopied head with scroll ornament over. The interior of the porch is roofed with pointed barrel vaulting, having ribs springing from carved corbels. The door to the church is square headed and is surmounted by a niche, which formerly contained a statue of the Blessed Virgin.
