“Glenstone is a 21st-century version of the Frick, the Phillips Collection or the Isabella Stewart Gardner Museum. And it’s the equivalent, among its contemporaries, of such celebrated art sanctuaries as Naoshima in Japan and Louisiana in Denmark. … Even as you sigh and breathe more deeply at Glenstone, you can’t help but feel that the people who set all this up — a billionaire couple who live on the property — have designs on you. And part of you — or part of me, anyway — wants to resist.” – The Washington Post
