Derneford, Nicholas de (fl. 1309–31). English mason. He seems to have been a specialist in military architecture and fortification, was master-mason at Beaumaris Castle (from 1316), and Master of the Works at Caernarfon, Conway, Criccieth, and Harlech Castles in Wales from 1323. In 1327 he was also put in charge of the castles at Aberystwyth, Cardigan, and Carmarthen. In addition, he may have designed the exquisite choir at St Augustine's Church, Bristol (now the Cathedral), built 1298–1340, in which case he was an architect of great originality.
