[1124] Tiles are not used in the Tower, but some of the older arches of the arcade on the top floor have voussoirs of rag, evidently continuing the tradition of tiles. Most of the arches at Colchester are headed with tiles.
[1125] The room supposed to be the chapel in Bamborough keep has a round apse, but with no external projection, being formed in the thickness of the wall. The keep of Pevensey has three extraordinary apse-like projections of solid masonry attached to its foundations. See Mr Harold Sands’ Report of Excavations at Pevensey.
[1126] “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.
[1127] It is well known that blocks of huge size are employed in Anglo-Saxon architecture, but generally only as quoins or first courses. See Baldwin Brown, The Arts in Early England, ii., 326.
