I have a couple of questions please: 1) So, how exactly would YOU know the manner in which 'the Ancients' used 'these places'? Please share your sources. 2) (which raises the obvious follow-up) so how do you define 'these places'? Are you limiting your comments to Neolithic funerary monuments - such as Wayland Smithy - which the archaeology strongly suggests were communal, so MAY have been places of noisy celebration at given times... although, then again, whatever 'priestly caste' presumably held sway may well have enforced silence? Or are you also including the many, many thousands of Bronze Age sites, many of which are seemingly located as to be only accessible to a limited percentile of the population? Is it safe to assume... let alone purport to 'know'... what etiquette was applicable to THESE places? Please be specific. The only fact I can see here is: we do not know.
It would appear to me - as an amateur interpreting the published views gleaned from archaeology best I can.. and using this understanding to inform personal judgments based upon many, many hours in the field - that Prehistoric monuments possessed differing functions, evolving over time. Are you implying a site such as, say, the great cairn of Aran Fawddwy, was a communal meeting place to go and have a party? If so, why was it placed there ... and who was left behind?
I do find it very sad that we live in a society where the 'me first' outlook is so much to the fore... and others appear to not give a damn. Clearly, there is much subjectivity involved depending upon the situation. However, in my opinion, people who do not consider others are well worthy of censure.
