As with most sites of this type, its true history is unknown. The name of the circle may derive from 'micel' or 'mycel', Old English for 'big', referring to the size of this large circle. Its doleritic stones came from nearby Stapeley Hill. Many of them are now missing and others are fallen. One example, reported in pagan magazine White Dragon, is that “This circle was the site of vandalism by a local farmer in the summer of 1995 when several stones were uprooted by a mechanical digger. The stones were promptly righted and "planted" again and the culprit punished. Ongoing unsympathetic use by both local youth and townie pagans, such as the creation of numerous fire pits and the leaving of litter and broken glass after the festivals, does nothing for the atmosphere of this site.” In the beginning there may have been some thirty stone pillars. The survivors that still stand range in height from 10ins to, and stand in an ellipse NW-SE by The tallest is at the south-east end of the major axis, standing, perhaps by coincidence or design, close to the line of the southern moonrise. This pillar and a companion have been taken to flank an entrance about wide. Aubrey Burl has stated in his 2000 book A Guide to the Stone Circles of Britain, Ireland and Brittany that "There was a claim for a central stone and a very dubious eighteenth-century report that 'there was a stone across your two Portals, like those at Stonehenge, and that the stone at eighty yards distance was the altar.'" but that the "probability of a trilithon, otherwise unique to Stonehenge, at Mitchell's Fold, like an identical claim for Kerzerho in Brittany, should be regarded as rumour rather than reality."
Folklore
As with most sites of this type, its true history is unknown. However, there is a traditional folkstory that a giant whose marvellous cow gave unlimited amounts of milk used the circle until a malicious witch milked the cow, using a sieve until it was drained dry, as a result of which it fled to Warwickshire where it became the Dun cow. As a punishment, the witch was turned into stone and surrounded by other stones to prevent her escaping. What became of the giant is unknown. Local folklore also suggests this is the actual place where King Arthur withdrew Excalibur from one of the stones in the circle and then became king of the Britains. Burl goes on to state that "An intriguing fact does exist however. Aerial photographs have revealed mediaeval ridge-and-furrow ploughmarks not only running up to the ring but also through it as though this 'prehistoric' megalithic ring might postdate the Middle Ages!" It does not. In the Middle Ages, the whole area was simply thoroughly farmed. In recent times, referred to as Yrvasnth, the site has been home to Germanic pagan revivalism and ritual.
Other nearby prehistoric sites
The only other known stone circles in Shropshire are the Hoarstones, only 1½ miles northeast of the Fold, and the Whetstones, less than half a mile to the east of the Fold. So this area is a concentrated area of activity. Nearly all the latter's stones were blown up in the 1860s; now there is only a collapse of stones. When the last stone was uprooted in 1870 charcoal and bones were seen in its hole. The circle is north of Bishop's Castle, north of Corndon Hill over the Welsh border in the small village of White Grit and within a few miles of the Late Neolithic-Early Bronze Age picrite stone axe factory of Cwm-Mawr. To the south-east is a weathered cubical block on a small cairn. Along the path leading from the Fold which crosses Stapeley Common, home to the Cow Stone , or single standing Stone - Menhir and the Stapeley Hill Ring Cairn .
