The largest stone to the southwest of the circle.
Cairn to the north of the circle - looking southwest.
This is a typically small Derbyshire
stone circle with a nearby cairn
in an area that also contains two other circles - Barbrook
II and Barbrook III, as
well as Bronze
Age settlement sites, cairns and field systems. This is the southernmost
of the circles and contains a flattened ring of twelve or thirteen small
stones with only one (to the southwest) over a metre tall. This stone
seems to form an entrance with its neighbour but whether this is original
or not is unclear - there is a large gap in the stones to northeast too,
this could either have been an entrance or just missing stones. The ring
measures between twelve and fourteen metres in diameter and is surrounded
by the remains of a rubble bank about seventeen by nineteen metres at
its widest point. Barbrook I stands on gently southwest sloping land on
the west side of Ramsley Moor as it leads down to the stream of Bar Brook
- from where the three circles on the moor take their names. From here
there are views west across Big Moor and the settlement sites around Swine
Sty with more distant vistas over Derbyshire to the southwest.
While there have been few finds from the circle, the cairn that stands
a short distance to the north was excavated and then restored during the
early 1980's and was found to contain four cup
marked rocks, one which also had a ring.
