 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 .
