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. BLANTYRE PRIORY, LANARKSHIRE. The fragmentary ruins of this structure are situated on the left bank of the Clyde near Bothwell, at a point where the river forms a sudden bend from west to north, and where the priory is confronted on the opposite side by the great donjon of Bothwell Castle. The eastern walls of the priory stand on the very edge of a precipice, which rises perhaps 80 or 100 feet above the river. The buildings at this part are situated on fairly level ground, but immediately to the west the ground rises rapidly, so that the cloister garth (Fig. 1417) and the western enclosing walls are on a considerably higher level than the main buildings. The ruins cover a space of ground measuring about 150 feet from east to west by about 115 feet from north to south. The western enclosing wall is from 5 to 10 feet in height, and the northern wall stands to the height of about 10 feet. The southern wall is nearly all gone, except a part at the return of the buildings at the east and west ends. At the north-east corner stands a two-storied structure, the walls of which, except the south one, are almost entire. This was probably the prior’s house. It enters by a doorway at the west end of the south wall, and adjoining the door there appears to have been a stair to the upper floor (which is the floor shown on the Plan), but the place is in so confused a state with ruins and vegetation, that little regarding its arrangement can be made out. The house contained two rooms, one at each end, with the stair between. There are a fireplace and a window in each gable, and the eastern window looks straight across the river to the castle donjon. Along the north side of the house the ground is steep and inaccessible. On the south side of this house there was a courtyard with a building at the east end, the end wall of which still stands two stories high, in continuation of the gable of the prior’s house.
