The interior of the church (Fig. 1193) is very plain. The tower is supported on arches at the crossing, which spring from attached piers with moulded caps. The space over the crossing is vaulted with groins, having a circular boss in the centre. The tower (see Fig. 1188) is carried up with plain walls to two stories above the roof, and has in the upper [Illustration: FIG. 1191.--St. Mary’s, Whitekirk. View from North-West.] part or belfry a window on each side, with central mullion, now much decayed by the weather. A stair turret (Fig. 1194) is attached to the north-west angle of the tower, and enters from the exterior. The north wall of the nave has been altered at the point adjoining the tower. At a distance of about 100 yards north from the church stands a plain [Illustration: FIG. 1192.--St. Mary’s, Whitekirk. South-West Porch.] building (Fig. 1195), which is believed to have been the tithe barn of the parish. It is situated on the edge of a rocky ridge which slopes steeply [Illustration: FIG. 1193.--St. Mary’s, Whitekirk. Interior, looking East.] downwards on the north side. In the view (Fig. 1196) taken from the low ground on the north side the top of the church spire is seen. The barn measures about 65 feet 4 inches in length from east to west, by about 20 feet in breadth over the walls. It has been built at two periods. The western portion, measuring on the outside about 21 feet 3 inches by 20 [Illustration: FIG. 1194.--St. Mary’s, Whitekirk. The Tower, from North-West.] feet, has originally been a pele tower, with walls about 5 feet in thickness, and was altered at a later period, when it was extended into a barn. The present entrance to the keep is in the south wall, which appears to have been rebuilt of the same reduced thickness (2 feet 4 inches) as the barn walls. This doorway leads into a vaulted ground floor, from which a door [Illustration: FIG. 1195.--St. Mary’s, Whitekirk. Plans of Tithe Barn.] to a small lobby gives access to a narrow straight stair leading to the first floor, contained in the thickness of the north wall. The stair is lighted [Illustration: FIG. 1196.--St. Mary’s, Whitekirk. Tithe Barn, from North-East.] with narrow slits, and the door at the top leading into what was originally the hall is finished in the way usual in such structures, with well wrought splays round the stone jambs and lintel. On the first floor the east wall of the pele tower has been taken down. The junction of the tower with the barn is plainly visible from the rough face of the masonry in the interior of the north wall, where the east wall of the tower has been cut away. The upper part of the tower being thus thrown into the barn, a few steps, as shown on the Plan, lead up to the latter. There is an upper floor in [Illustration: FIG. 1197.--St. Mary’s, Whitekirk.
