Note 252 — CHAP. XVI.

Several of the glazed figured tiles used by the Normans, commonly called Roman tiles, patched up in different parts of the ruin, and a few Roman bricks built in the heterogeneous mass that composes the grout-work of the walls, have occasioned many persons to consider the castle as of Roman foundation. But these circumstances, standing alone, afford very inconclusive grounds. On the Normans building the castle, the Roman fragments were most probably brought from the then decaying town of Caerwent, and with other rubbish applied to the work.
