Alexander Thom L1 / 7 Class III Survey
Construction: Type B flattened circle (Li/7). Diameter 359 ft = 131.9 my. Perimeter 390.0 my = 156.0 mr. The flow of the earth down the slope may have displaced the stones, leaving the more deeply set stones slightly behind. Long Meg as seen from the construction centre indicates the setting midwinter Sun and seen from the same centre the stones at Little Meg (Li/8) indicate the Sun rising at May Day/Lammas.

Aubrey Burl (Cumberland 23)
This is one of the largest British rings. It is in State care. It was built on a slope at 100 m O.D., 2 1/4 miles N of Langwathby. It is about 359 x 305 ft (109 x 93 m) in diameter.
Some 70 local porphyritic stones remain of a ring flattened at the N. 2 massive blocks stand at the E and W of the circumference. There are traces of a bank at the SW. 2 large stones at the SW define an entrance. 25 m beyond this is Long Meg* a red sandstone pillar possibly brought from the Eden valley i| miles away. Its SE face has several carvings of rings and spirals on it.
John Aubrey reported that 2 large cairns stood at the centre of the ring. William Stukeley noticed remains in 1725 but they have now gone.
There is a tradition that the ring has been disturbed and rebuilt.
