The building that houses the Salvador Dali Museum is a work of art in and of itself. The Yann Weymouth–designed structure is a simple-looking concrete rectangle with hurricane-proof walls that are 18 inches (46 centimeters) thick. From the building protrudes a large geodesic glass bubble known as the Enigma, which is comprised of 1,062 triangular pieces of glass, stretches 75 feet (23 meters) at its tallest point, and is an homage to the dome on Dali’s museum in Spain. Inside is a unique white helical staircase, echoing Dali’s passion for spirals and fascination with DNA.
