Snowdonia National Park Authority has voted to refer to Wales' highest mountain, which attracts more than 400,000 walkers a year, by its Welsh name. The decision came after thousands of people signed a petition calling for the change.
Rather than Snowdon and Snowdonia, the mountain and mountain range will now be referred to as Yr Wyddfa and Eryri. The authority said that it took "decisive action" after more than 5,000 signed a petition calling for action to be taken.
The motion to stop using the English names had been put forward in April by Gwynedd councillor John Pughe Roberts. The park's head of cultural heritage Naomi Jones said that Welsh place names were part of Eryri's "special qualities", and added that many public bodies already used the Welsh names.
