Designed by famed Italian architect Renzo Piano and set in a quiet section of Montrose, the building (1987) that houses the Menil Collection is hailed as a masterpiece of modern architecture. In fact peers recently named it the second most significant piece of architecture built in the last three decades worldwide. One remarkable aspect—the horizontal concrete columns along the roofline that funnel natural light into the numerous galleries. Also on the Menil’s campus, you’ll want to visit the non-denominational Rothko Chapel (1971) and Richmond Hall (1930), which houses a mesmerizing light installation from Dan Flavin.
