Archaeologists are aware of around twelve Neolithic long barrows that are located in Kent. The best known of these are the Medway Megaliths, all of which are found in the vicinity of the River Medway and each of which contains a stone burial chamber. This use of stone as a building material sets these Medway Megaliths apart from Julliberrie's Grave and the Stour long barrows. The decision by the builders of the Stour long barrows to not use stone was likely deliberate, for sarsens are naturally present in the local area and could have been obtained had they wanted them. Archaeologists recognise the Stour long barrows as a distinct regional grouping of this form of monument. The archaeologist Paul Ashbee thought that there was a typological link between Julliberrie's Grave and the long barrows on the chalk downlands of Sussex, despite the fact that they are over fifty miles apart from each other. The three tumuli are located within eight kilometres of each other, high up on the North Downs between Canterbury and Ashford. As of 1998, Julliberrie's Grave is the only one of the trio to have been archaeologically excavated.
