The video interprets Scottish engineer Alexander Thom's survey of Moel Tŷ Uchaf as revealing a five-pointed star and a sevenfold arrangement. It says Thom plotted each stone's centre of gravity, that five points define the circle's curves, and that each opening in the seven-pointed star contains seven stones. The circle sits on a 1,449-foot (about 442-metre) hill near Llandrillo in North Wales. Calling it "one of Britain's most sophisticated stone circles" is the presenter's assessment, not an established archaeological classification.
