You have to see this lakeside institution, which features a stunning winglike addition by Santiago Calatrava. It soars open and closed every day at 10am, noon and 5pm (8pm on Thursday), which is wild to watch; head to the suspension bridge outside for the best view. There are fabulous folk and outsider art galleries, and a sizeable collection of Georgia O'Keeffe paintings. A 2015 renovation added photography and new media galleries to the trove.
