Mitchell's Fold Stone Circle Mitchell's Fold (sometimes called Medgel's Fold or Madges Pinfold) is a Bronze Age stone circle in southwest Shropshire, located in the civil parish of Chirbury with Brompton, at a height of 1083 ft (330m). Coordinates 52.578657,-3.028153 Stones There are 12 stones currently, of which 3 are tall and 9 are small with some part buried. Using the angles 4° and 18° clockwise and then the angle 26° the following are produced, the angles 4° and 18° produce the 26° and 12° angles. 4° clockwise 1,1,1,1,1,1,1,2,2,1 18° clockwise 2,1,1,1,2,2,1,2 4° 1×1×1×1×1׳√(221)=6.046 18° 2׳√(2212)=26.059 26° 2,1,1,1,1,1,2,1,2 After using the 26° aligning with the tallest stone, a 26° northeast angle gives the following, probably as an alignment check. 2,1,1,1,1,1,1,1,1,2 Taking each of the three angles and numbers produced aligns best as below, although there are '1's or '2's where there should be a '2' or '1'. 1,1,1
