Sheltering piered walls

2033. Sheltering piers were formerly, in some cases, made of such a width and depth as to contain a niche for training a vine, and, in that case, they were frequently raised above the coping of the wall. Examples of such piers exist in the walls of the kitchen-garden at Claremont, built from the designs of Brown, and at Hatton, in Scotland, built after a design by London and Wise.
