The post medieval field system at Pentre Dolau Honddu on the valley slopes on either side of a stream. The field system directly connected with Disgwylfa and with Blaen y Cwm have been given separate numbers, NPRNs 242146 and 242002. The boundaries of the field system are still largely intact, although the ground within is now very rough with coarse grass and reeds. J.J. Hall, Trysor, 8 June 2008
