Many archaeologists have suggested that this is because Early Neolithic people adhered to an ancestor cult that venerated the spirits of the dead, believing that they could intercede with the forces of nature for the benefit of their living descendants. It has furthermore been suggested that Early Neolithic people entered into the tombs – which doubled as temples or shrines – to perform rituals that would honour the dead and ask for their assistance. For this reason, historian Ronald Hutton termed these monuments "tomb-shrines" to reflect their dual purpose. In Britain, these tombs were typically located on prominent hills and slopes overlooking the surrounding landscape, perhaps at the junction between different territories. Archaeologist Caroline Malone noted that the tombs would have served as one of a variety of markers in the landscape that conveyed information on "territory, political allegiance, ownership, and ancestors." Many archaeologists have subscribed to the idea that these tomb-shrines served as territorial markers between different tribal groups, although others have argued that such markers would be of little use to a nomadic herding society. Instead it has been suggested that they represent markers along herding pathways. Many archaeologists have suggested that the construction of such monuments reflects an attempt to stamp control and ownership over the land, thus representing a change in mindset brought about by Neolithicisation. Others have suggested that these monuments were built on sites already deemed sacred by Mesolithic hunter-gatherers. Archaeologists have differentiated these Early Neolithic tombs into a variety of different architectural styles, each typically associated with a different region within the British Isles. Passage graves, characterised by their narrow passage made of large stones and one or multiple burial chambers covered in earth or stone, were predominantly located in northern Britain and southern and central Ireland. Alternately, across northern Ireland and central Britain long chambered mounds predominated, while in the east and south-east of Britain, earthen long barrows represented the dominant architectural trend. These earthen long barrows were typically constructed of timber because building stone was scarce in southern Britain; archaeologist Aubrey Burl argued that these timber tombs might have been "even more eye-catching" than their stone counterparts, perhaps consisting 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. 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.
