Damaged ornamentation

On the upper stage, all elevations, there is some significant damage. On the topmost section to the south elevation there is quite extensive deterioration to the quatrefoil and trefoil ornamentation; along with complete stone loss to some finer carved sections (e.g. cusps). This had almost certainly been caused by a combination of poor water discharge from the string course over, an increased amount of exposure at this level and aspect.
