Visited on 24th May 2011 on the way back from Long Meg and Her Daughters.
Information board says that this huge henge has a circumference of 150 metres and was built from 5 million cobblestones brought from the nearby River Eamont many of which have now been removed for building materials. It varies in height from 4 metres to 7 metres and has no internal or external ditch. There were 4 large stones at its centre though only one remains. There were also 4 stones standing at a single 7 metre entrance to the east – these too are gone.
The nearby King Arthur’s Round Table can be clearly seen from Mayburgh Henge.
