use; in this scenario, the monuments would be composite structures. The builders were probably influenced by pre-existing tomb-shrines. Whether those people had grown up locally, or moved into the Medway area from elsewhere, is not known. Based on a stylistic analysis of their architectural designs, the archaeologist Stuart Piggott thought that the plan behind the Medway Megaliths had originated in the area around the Low Countries; conversely, Glyn Daniel thought their design derived from Scandinavia, John H. Evans thought Germany, and Ronald F. Jessup suggested an influence from the Cotswold-Severn group. Ashbee noted that their close clustering in the same area was reminiscent of the megalithic tomb-shrine traditions of continental Northern Europe, and emphasised that the megaliths were a regional manifestation of a tradition widespread across Early Neolithic Europe. He nevertheless stressed that a precise place of origin was "impossible to indicate" with the available evidence. Features Lower White Horse Stone The Lower White Horse Stone once stood about west of Upper White Horse Stone. It was located to the north-west of where the Pilgrims' Way bisected the Rochester-to-Maidstone road, with the latter now being the A229 dual carriageway. Philp and Dutto thought that the site of the Lower White Horse Stone was probably under the A229. Evans called this the "Original White Horse Stone", but noted that it was sometimes known as "The Kentish Standard Stone". Apparently also made from sarsen, the stone was broken up prior to 1834. It is possible that the Lower White Horse Stone was part of a former chambered long barrow, although Philp and Dutto noted that any such link was "uncertain". Upper White Horse Stone The Upper White Horse Stone () is in length, in height, and about thick. It is sarsen. The White Horse Stone is situated in "a narrow strip of woodland", known as Westfield Wood, which is adjacent to the Pilgrim's Way. The megalith lies to the east of the A229 dual carriageway, and can be reached by going behind the nearby petrol garage and following the Pilgrim's Way. The Upper White Horse Stone took its name from the destroyed Lower White Horse Stone; that it had taken on this name was first noted in print in 1927. Reflecting this, Evans called it the "Successor White Horse Stone". He believed that at one end it had the "crude outline of a face caused by the natural configuration of the rock".
