The medieval parish of Llandudno comprised three townships all established on the lower slopes of the Great Orme. The township of Y Gogarth at the south-western 'corner' of the Great Orme was latterly the smallest but it contained the palace of the Bishop of Bangor. The Manor of Gogarth (which included all three townships) had been bestowed on Anian, Bishop of Bangor by King Edward I in 1284 in recognition of services rendered to the crown, notably the baptism of the first English Prince of Wales, newly born at Caernarfon. The palace was burnt down by Owain Glyndŵr in 1400 and the ruins have mostly been washed away together with much of the township by coastal erosion in the Conwy Estuary.
