A roofless ruin (Fig. 1416), about two miles south of Gatehouse, with
walls fairly entire. It measures internally about 71 feet long by about
20 feet wide, and is lighted by windows in the south wall, and two high
narrow windows in the east end, over which, in the apex, there is a
shallow niche. There is only one small high window in the north wall.
[Illustration: FIG. 1416.--Old Girthon Church. Plan.]
The entrance door is in the south wall, not far from the centre of the
church. In each end of the church there is a doorway, but these are
probably modern. In the south wall, near the east end in the usual
position of the piscina, there is what Mr. Coles calls an ambry,
roughly formed out of a single stone. It is surrounded with a large
hollow moulding 4 inches wide, over which it measures 1 foot 8 inches
wide by 2 feet 6 inches high, and 9 inches in depth.
Mr. Muir[191] classes Girthon with a number of other churches which may
be either of the Norman or first pointed period.
