The Beinecke Rare Book library at Yale is stunning when you see it in person. No windows. The egg-crate look is all marble and when you’re inside the marble walls glow from the outdoor light. The filtered light also protects the books. It’s all kinds of gorgeous. This photo makes it look hideous though. https://beinecke.library.yale.edu/visit
The Bard concert hall designed by Gehry is also stunning in context. It shimmers against the backdrop of the Hudson River, like sails on a sailboat. – https://www.youtube.com/watch?v=QV8wei2shAw
In general I like the mix of old New England clapboard house-type architecture, red Vermont barn-esque architecture and sheer modern structures of Bennington College.
