Barbrook I is an embanked stone circle with a substantial stone cairn. It sits on a shelf of ground raised a little from the track, but lower than the moor behind it, so it cannot be viewed from either of the other circles to the north. here are 12 stones in a ring varying in diameter from 12.5 to 14.5 metres in an excellent example of a flattened circle, the bank is not a prominent feature. Only one stone rises above a metre in height, and it is quite markedly taller than the others. When the cairn above Barbrook I was excavated and restored in the early 1980's four carved stones were found. A rectangular slab with a cup and ring marking, a triangular slab with 4 cup marks along an edge, a single cup mark on small slab and a slab with 2 cups on one side and one on the other. All the stones are stored in the Weston Park museum in Sheffield.

Barbrook II was extensively excavated in the 1960's and restored in 1989. The circle is now probably much as it was around 2000BC The irregular ring of standing stones is set in a drystone wall retaining the inner edge of a rubble bank, with an entrance to the north east. Only one standing stone is significantly higher than the bank. A small cairn is located in the interior. Four human cremations were deposited in the south western half of the interior, two in simple pits, one in a pit under a small cairn, and one in a small burial box known as a cist.

Barbrook III also known as Owler Bar, the Ordnance Survey map shows the ring in the wrong place, just follow the path and you will find it. It is very difficult to make out, as most of the stones are almost completely overgrown by the moorland grass but a ring can be seen.

Barbrook IV has sometimes been referred to as a stone circle, but is more likely to be a ring cairn. All that remains is a rubble bank circa 23m by 21m externally in diameter.

Barbrook V is part of the extensive cairn field, it lies to the west of Barbrook I stone circle. It has been badly damaged by a pack horse track which cut through the centre in the Medieval period and only half of the bank to the south-east remains. The settlement at Swine Sty is only a couple hundred metres or so away.
