Note 1126 — Chapter XII · STONE CASTLES OF THE NORMAN PERIOD
Reading edition
“In the course of the 12th century, the base of the walls was thickened into a plinth, in order better to resist the battering ram.” (Manuel d’Archæologie Française, ii., 463.) The keep of Pevensey has a battering plinth which is clearly original, and which throws doubt either on this theory of the plinth, or on the age of the building.
