Welsh names Yr Wyddfa and Eryri will be used instead of Snowdon and Snowdonia.

Snowdonia National Park Authority has voted to use the Welsh names Yr Wyddfa and Eryri rather than the English equivalent of Snowdon and Snowdonia. Yr Wyddfa is the highest mountain in Wales, and stands at 3,560 feet (1,085 metres) above sea level. Eryri is the mountainous region in northwestern Wales and a national park of 823 square miles (2,130 km2) in area in which Yr Wyddfa stands.

The change comes after concerns were raised about long established Welsh place, house, rock and mountain names being eradicated and changed into English. Naomi Jones, the park's head of cultural heritage, said: "By referring to our most renowned landmarks by their Welsh names, we give people from all over the world the opportunity to engage with the Welsh language and its rich culture." 

The Welsh Yr Wyddfa, means grave and is pronounced like "er with-va". In legend it is said that the giant Rhita Gawr, the king of Wales, was buried under a cairn of stones on the summit of the mountain, following a battle with King Arthur. The story tells of the giant defeating 30 kings of Britain, taking their beards to create a cloak of the beards, reaching from his shoulder to the floor.
