Prince Llywelyn of Gwynedd's favourite dog is Gelert, a fearless hunting dog and loyal friend and companion who was said to have been a gift from King John of England.

Gelert's Grave - or Beddgelert in Welsh - is located south of the village along the River Glaslyn, marking the brave dog's final resting place. His heroic story is inscribed on his tombstone.

He later found his son safe alongside a dead wolf, which had been killed by Gelert. Llewelyn is said to have never smiled again. The dog's grave can be found at Beddgelert, Snowdonia.
