The Carneddau, Snowdonia, Conwy, Wales
Carnedd Gwenllian was formerly known as Carnedd Uchaf (in 2009) and as Garnedd Uchaf prior to that.
Carnedd Gwenllian (Carnedd Uchaf) means 'Gwenllain's Cairn (High Cairn)' in Welsh.
The summit of Carnedd Gwenllian (Carnedd Uchaf) is marked by a rocky outcrop.
Gwenllian of Wales (June 1282 - 7 June, 1337) was the only child of Llywelyn ap Gruffudd, the last native Prince of Wales. After a long campaign by the Princess Gwenllian Society, the OS agreed to use the dual name Carnedd Gwenllian/Carnedd Uchaf on it's maps from 2010 onwards.
