PANT CAD IFOR Enwyd y fan hon ar ôl Ifor Bach, y pennaeth o Gymro a lwyddodd i fynd i mewn i Gastell Caerdydd yn 1158 a chipio William Fitzcount, Arglwydd Morgannwg, a'i deulu yn wystlon. Dim ar ol cael y tir a oedd wedi ei gymryd oddi arno, a llog, y cytunodd i ryddhau ei wystlon. PANT CAD IFOR Named after Ifor Bach, a Welsh chieftain who in 1158 is reputed to have crept into Cardiff Castle taking hostages, namely William Fitzcount Lord of Glamorgan, and his family, only releasing them when his stolen land was returned with interest.
