Note 1049 — Chapter XI · MOTTE-CASTLES IN IRELAND
Reading edition
That a motte-castle of earth and wood seemed to Giraldus quite an adequate castle is proved by the fact that numbers of the castles which he mentions have never had any stone defences. It may be a mere coincidence, but it is worth noting, that there are no mottes now at any of the places which Giraldus mentions as exilia municipia, Pembroke, Dundunnolf, Down City, and Carrick.
