Rare chance to see archaeological work at a Welsh Prince's forgotten castle
Members of the public are being given the rare opportunity to see archaeological work being carried out at Castell Carndochan in Snowdonia National Park.
The event is part of Cadw's 'Open Doors' scheme, which is being run in partnership with the Park Authority and Gwynedd Archaeological Trust.
Castell Carndochan stands on a rocky hill not far from Llanuwchllyn, and was probably one of Llywelyn ab Iorwerth's castles built to protect the area during the Thirteenth Century.
There is however evidence that the site was also used as a fort in prehistoric times and a decorated glass bead from the Iron Age was recently discovered there.
Those wishing to visit the site can take advantage of three guided tours of the site at 1030, 1400 and 1830.
