as Coldrum's rectilinear shape, the Chestnut Long Barrow's facade, and the long, thin mounds at Addington and Kit's Coty. These variations might have been caused by the monuments being altered over the course of their use. The builders were probably influenced by pre-existing tomb-shrines. It is not known if these people had grown up locally, or moved into the Medway area from elsewhere. 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. Design The part of the chambered long barrow that was discovered was a stone chamber composed of four large stones. The stones used were sarsens. The northern stone measured by by . The southern stone measured by by . The third stone, on the western side, measured by by . A fourth, smaller stone, measuring by by , was placed to prevent the north stone falling onto its southern counterpart. This may have once been used to divide the chamber in two. Given the recorded dimensions of the stones, Ashbee suggested that the chamber may have once measured in length and could have included as many as ten sarsen stones in its original construction. He also suggested that it would have had a height of around , making it one of the smaller chambers in the Medway region; the chamber at Kits Cot House, for instance, reached over in height, and that at Chestnuts Long Barrow reached a height of about . Below these megaliths was a flat stone, measuring in length and in width. Lying atop this stone were human remains, reportedly aligned in an east to west orientation. Ashbee noted that such paving stones are rare in recorded chambered tombs, and suggested that it might instead have once been a cover stone that sat atop the chamber, but which had been knocked down at some
