In a cultivated farm field, a venerable old standing stone along with some fallen stones on the remains of a long barrow, now just a small mound. A small leafless tree growing next to it - an elder I think.
Visited today on a bright, chilly afternoon; near the Cotswold village of Daglingworth in the Duntisbourne Valley is the Hoar Stone long barrow. The field next to it has a locked gate (easily climbed) and a gap in the field hedge for access. I did it the hard way as usual; climbed over a barbed wire fence into the actual field getting caught on both fence and blackthorns in the process. Glad to report no serious injury and jeans still intact.
In Old English 'se harne stan' - hoar stone indicates the boundary between the known, familiar world of human activity and the frightening realm of monsters and the supernatural. Also means 'grey-haired with age, venerable' which seems about right.
Just up the lane to the left, is Duntisbourne Barrow - two mounds in Cherry Wood (notice on gate saying walkers welcome). I understand these are the remains of one very large long barrow - much evidence of past excavation and damage.
Celia Hadon suggests that the stones at this barrow may be 'running stones':
This is no 14 in Old Stones of the Cotswolds by D.P. Sullivan (Reardon). These may be the hoar stones of which it is said that they run round the field when they hear the nearby church clock strike the hour.
The field in which the stone lies is called the 'Devils Flights', and it is said that the stones sometimes turn over at midnight - presumably if they haven't got the energy for the activity Kammer mentions above.

If you're in the area, you might be interested in following this up, which I saw mentioned in an article on 'Gloucestershire Barrows' in the 1989 volume of the Trans Brist Glouc Arch Soc...
Just 'round the corner' from the Hoar Stone was the Jack Barrow - at SO957071, judging by its position on the map at old-maps.co.uk - on the land of Jackbarrow farm, in fact.
The barrow was destroyed/excavated in Victorian times - but the excavators "considerately" took the bones and reinterred them at the church in nearby Duntisbourne Abbots (at SO971078), popping a nice stone cross on top. I suppose their hearts were in the right place.
The NMR (available via the MAGIC web site) describes the site:
The monument includes a long barrow situated on a south east facing slope below the crest of a wide spur. The long barrow is orientated east-west but has been rounded by cultivation. The mound is 48m long and has a maximum width, at the centre, of 28m. It reaches a maximum height of 0.8m in the part that is no longer under cultivation but elsewhere survives as a slight rise approximately 0.3m high. Set into the east end of the mound is a large, lozenge shaped stone, known locally as the Hoar Stone. To the south of the centre of the mound is a large, kite shaped, capstone which covers a chamber. This was excavated in 1806 by Anthony Preston and is reported to have been divided into two segments and to have contained the remains of eight or nine skeletons. Although no longer visible on the surface, quarry ditches will flank either side of the mound and will survive as buried features 3m wide.
On her web site Celia Hadon recommends a visit during the Autumn or Winter when the field is not full of crops.
"Sept 1806. A large oblong Barrow was open'd in the Parish of Duntesbourne Abbots Gloucestershire; in which was found a Kistvaen containing about eight or nine Bodies of different Ages..."
