 Archaeologists have established that the monument was built by pastoralist communities shortly after the introduction of agriculture to Britain from continental Europe . Although representing part of an architectural tradition of long barrow building that was widespread across Neolithic Europe , the Coldrum Stones belong to a localised regional variant of barrows produced in the vicinity of the River Medway , now known as the Medway Megaliths . Of these , it is in the best surviving condition , and lies near to both Addington Long Barrow and Chestnuts Long Barrow on the western side of the river . Three further surviving long barrows , Kit 's Coty House , the Little Kit 's Coty House , and the Coffin Stone , are located on the Medway 's eastern side .
