FourWinds,
I think it's obvious that the 20th Century restorations of Avebury and Stonehenge weren't done for money, it's just that the charge to get in (to Stonehenge) occured after. At least (as claimed) the charge by English Heritage is non-profit-making. Well, lets just accept that for now, because that's not the purpose of this post.
If restoration is the be all and end all of things, how come very little has gone on since the 1930s? I think it's unfortunate that the restoration occured before the archaeological techniques were as good as they are today. No doubt in 100 years time someone else will say the same about digs in our time. At least we can appreciate some sites post-restoration.
What pisses me off is the mentality of the previous generations to try and destroy these anciant sites in the name of religion. The Christian religion preaches tolerance, but that same religion was intolerant towards pagan sites.
Cheers,
TE.
