The south wall of the nave has been removed, probably when a south aisle was added. Its place was, doubtless, at one time supplied by pillars and arches, but they are now gone. Part of the outer wall of the south aisle still remains. To the south of this there is a small building, which may have been a sacristy, or perhaps a tombhouse. The north door to the nave is still partly preserved, and there was probably a south door opposite it. In the west end, which still exists (see Fig. 680), there is a simple pointed window, greatly splayed within. The walls are built with freestone ashlar. All the features seem to indicate that the church was erected in the thirteenth century, although it has been surmised that it was rebuilt in the fifteenth century. The simplicity of the chancel arch and the absence of an east window are against that supposition. PRESTONKIRK CHURCH, HADDINGTONSHIRE. [Illustration: FIG 681.--Prestonkirk Church. Plan.] [Illustration: FIG. 682.--Prestonkirk Church. Details of Buttress and Window.] This church, like several others in the eastern part of this county, is dedicated to St. Baldred of the Bass Rock.[103] It is situated within a mile of East Linton Railway Station. The church has originally been a first pointed edifice, but now there only survives a small eastern choir of that period, the main body of the church having been rebuilt. The choir (Fig. 681), which is now cut off from the church by a solid wall, is 15 feet long by 17 feet 6 inches wide internally. It has three tall lancet windows of equal height in the east end (Fig. 683), separated by first pointed buttresses of good form, as seen in the detailed sketch (Fig. 682). The south wall has two simple lancets with hood moulds, and on both sides there is a broad set-off below the windows. The north wall is plain, and without special features. The building is a pleasing fragment of first pointed work. [Illustration: FIG. 683.--Prestonkirk Church. View from South-East.] COWIE CHURCH,[104] KINCARDINESHIRE.
