of "towering carved poles, flamboyantly painted", but that evidence of such sculptures has not survived. The Medway Megaliths represent just one of these regional groups within the wider West European tradition of tomb building in this period. Description Although now all in a ruinous state and not retaining their original appearance, at the time of construction the Medway Megaliths would have been some of the largest and most visually imposing Early Neolithic funerary monuments in Britain. Grouped along the River Medway as it cuts through the North Downs, they constitute the most south-easterly group of megalithic monuments in the British Isles, and the only megalithic group in eastern England. Archaeologists Brian Philp and Mike Dutto deemed the Medway Megaliths to be "some of the most interesting and well known" archaeological sites in Kent, while archaeologist Paul Ashbee described them as "the most grandiose and impressive structures of their kind in southern England". The BBC Countryfile website notes that although none of the monuments are on the same scale as Stonehenge, they are "really quite impressive" when taken collectively, describing them as "the east of England's answer to the megaliths of the Salisbury Plains". They can be divided into two separate clusters: one to the west of the River Medway and the other on Blue Bell Hill to the east, with the distance between the two clusters measuring at between 8 and 10 km. The western group includes Coldrum Long Barrow, Addington Long Barrow, and the Chestnuts Long Barrow. The eastern group consists of Kit's Coty House, Lower Kit's Coty House, the Coffin Stone, and several other stones which might have once been parts of chambered tombs. It is not known if they were all built at the same time, or whether they were constructed in succession, while similarly it is not known if they each served the same function or whether there was a hierarchy in their usage. The Medway long barrows all conformed to the same general design plan, and are all aligned on an east to west axis. Each had a stone chamber at the eastern end of the mound, and they each probably had a stone facade flanking the entrance. The chambers were constructed from sarsen, a dense, hard, and durable stone that occurs naturally throughout Kent, having formed out of silicified sand from the Eocene. Early Neolithic builders would have selected blocks from the local area,
