Didn't know that, interesting. It's hard to overstate the importance of Bennachie to the overall landscape and many megalithic sites round here isn't it? A wonderful hill.
Probably helps that it is smack bang in the middle of Aberdeenshire (except Laurencekirk area). It can be seen from Longmanhill Long Cairn near Banff, Forvie, Morven i.e the extremes of the Shire.
