Although Prince Llywelyn’s head was taken away to be displayed in London, it is said that his body was taken to Cwmhir Abbey by his followers, where it was laid to rest.
Er i ben y Tywysog Llywelyn gael ei gludo i’w arddangos yn Llundain, dywedir i'w ddilynwyr fynd â’i gorff i’w gladdu yn Abaty Cwm-hir.
