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.
