Mardon Down stone circle is the biggest by circumference on Dartmoor with a diameter of 38m. The site would have been impressive in its day and is one of the only ones sited on the top of high ground and has a fine view of the surrounding area. Today the circle is fairly dilapidated. Six stones remain upright and another 16 lie roughly in place. There are two massive megaliths one of which is on the north-western part of the circle. A short arc of seven stones remains in position on the south-east of the circle. The circle was first described by Dr Milles in 1772 who reported around 70 stones. Butler suggests it probably originally consisted of around 61 stones many of which are probably buried under the peat where they originally fell although some have no doubt been robbed out.
