It was also the spot where Owain Glyndwr was proclaimed Prince of Wales by his followers on September 16 1400.

The site is deemed of historical importance to Wales and, in January 2009, Welsh monument preservation society, CADW, announced it was to spend money on the site to protect its future.

The chief inspector of Welsh monuments told the BBC Radio Wales Roy Noble programme that without action there was concern the site, basically a mound of earth, was in danger of "slipping down the hillside".
