Brecon Beacons National Park has announced that it will use its Welsh language name only in future.

The switch - to Bannau Brycheiniog National Park - takes effect on its 66th anniversary.

Park bosses say the name change will help celebrate and promote the area's culture and heritage.

It is part of a wider overhaul of how the park is managed, to try and address serious environmental challenges.

The new name means "The Peaks of Brychan's Kingdom".

National park aims to welcome more diverse groups

Brycheiniog - named after 5th Century King Brychan - was an independent kingdom in the early middle ages, and its borders roughly match those of the national park today.
