Devil's Quoits The Devil's Quoits is a stone circle in Oxfordshire similiar to Castlerigg in Cumbria, which was restored in 2002 from being used as an airfield during WWII. It is thought to be Neolithic, and a complete plan was discovered during the excavation of the site. The site was levelled in 1940 for the war effort. Excavations in 1973 and 1988 located a complete plan with most restored. Of the 36 stones thought to have been there originally 29 remain, one of which is a marker. Devil's Quoits is a major class II circle henge and ditch up to 120 metres wide with the stone circle 79 metres, the marker points towards the southeast. As with other stone circles, the stones align, giving a sequence of 0's and 1's. These can also be 1's and 2's. The marker at 58° defines the limit to measure. Again, 11 is considered as √ or 11, and 1111 or 111 is considered as ³√. Considering both until the sequence is defined, the following is produced. (This is be
