The Grubstones (grid reference SE136447 ) is a stone circle on Burley Moor in West Yorkshire, England. It is believed to be either an embanked stone circle or a ring cairn.
The Grubstones circle is located on Burley Moor (to the east of Ilkley Moor). [1] It is situated below the top of the hill on a gentle south facing slope. [2] The circle is just over 800 metres (0.5 mi) south-east of the Twelve Apostles. [1] South-east of the circle there are several large cairns including The Skirtful of Stones. [3]
The circle has a diameter of about 10 metres (30 ft). [3] It is almost perfectly circular with twenty surviving stones. [3] The stones are set on the inside of a low bank, about 1.8 metres (6 ft) wide. [1] [2] The circle has been described variously as a cairn circle, a ring cairn enclosure, or a stone circle. [4] One third of the circle on the south side has been destroyed by shooting butts. [1] Four large loose stones in the interior may have come from this break. [2] The interior was excavated circa 1846 which revealed a cremation, accompanied by a flint spearhead. [2]
In the 20th century there was additional damage in the form of a subrectangular earthwork mound said to be an "orgone accumulator". [2] Orgone is supposed to be a vital energy or life force which informs the universe, and which can be collected and stored in an orgone accumulator for subsequent use in the treatment of illness. [2]
