They believed it afforded them and their people divine protection . It is not known when it first arrived in Gwynedd or how they had inherited it , but it is possible that it was brought back from Rome by king Hywel Dda following his pilgrimage in about 928 . According to tradition it was handed down from prince to prince until the time of Llywelyn ap Gruffudd and his brother Dafydd . Following the complete defeat of Gwynedd and the subjugation of the Principality , following the death of Llywelyn and the execution of Dafydd in 1283 , this holy relic was ready for English expropriation alongside the other spiritual and temporal artefacts ( see Llywelyn 's coronet ) of the Principality . The Alms Roll of 1283 records that a cleric named Huw ab Ithel presented this '' part of the most holy wood of the True Cross '' to Edward I of England at Aberconwy . It then accompanied the king as he finished his campaign in north Wales before being brought to London and paraded through the streets at the head of a procession in May 1285 which included the king , the queen , his children , magnates of the realm and fourteen bishops . What happened to the Cross of Neith after this is unknown .
