I wish someone would actually define ritual landscape as an actuality, without always vague references to a hill or a mountain in the distance... You can say Stonehenge has plenty of ritualised areas - cursus/avenue/stone circle/barrows, it could also be a great necropolis though and Avebury also has a similar amount of monuments but you could equally see such places as settlements where the build up of the above comes over time, similar to a town or city....
The Mendips for instance has'nt been given any 'ritual landscape' interpretation, though it has plenty of monuments to be deciphered yet, its longbarrows look more like territoral or boundary markers, as does of course some of the cromlechs in West Wales, which can also be found sometimes next to 'gorsedd' or rocky outcrops....all different, all puzzling, and all different time frames...
