The monument includes about 50 large limestone blocks, quarried from a local site, which form an egg-shaped circle. There were probably 41-43 stones originally, but some are now in fragments. They range in size from, with monoliths of between. One stone is partially upright; the rest are all lying flat. Although it is often stated that the stones have never stood upright, it is possible that they had originally been set upright in shallow stone holes. In the centre of the circle lie at least six smaller blocks, originally believed to have been set in a rectangle, known as the cove. The stones are surrounded by a massive earth bank, approximately at the outside edges and high, with an interior ditch about 2 m deep and wide. There are two causeway entrances breaching both the bank and ditch; a north-west entrance wide, and a south-east entrance wide. The inner bank encloses an area of. Few henge monuments in the British Isles are as well preserved.
Finds
Human skeletal remains were discovered close to the cove during excavations between 1901 and 1902. Other finds have included flint scrapers, arrowheads, and bone and antler tools.
Surrounding landscape
A large Bronze Ageround cairn or barrow was built later, to the east of the henge, using material taken from the earth bank. It was excavated in 1845 and found to contain a cremation burial, flint and bone artefacts, and two pots similar to Late NeolithicPeterborough ware now in the care ofSheffield City Museum. Arbor Low is part of a larger complex, and is linked by an earth ridge to the earlier Neolithic oval barrow of Gib Hill 320m away.
Construction and usage
The bank and ditch of the henge, as well as its two entrances, were probably established in the Late Neolithic period, with the stones added later, some time before 2000 BC. The site seems to have been in use until into the Bronze Age, which was when the outer bank was reconstructed so that the round barrow could be erected. Both the earthworks and the stoneworks are probably later than the nearby Gib Hill.
The henge stands on private farmland, but is accessible to the public. As of September 2019, an entrance fee of £1 per adult is requested. Children can enter free of charge.
