The Quadracci Pavilion is a striking addition to the Milwaukee Art Museum in Wisconsin, designed by architect Santiago Calatrava. Opened in 2001, it features a unique, sail-like design that symbolizes the city's connection to Lake Michigan. The pavilion houses galleries, a café, and a stunning glass-enclosed space that offers panoramic views of the lake. One of the most notable features of the Quadracci Pavilion is its brise soleil, a movable sunscreen that opens and closes like a bird's wings. This innovative design not only enhances the building's aesthetic appeal but also helps regulate natural light within the galleries, creating an inviting atmosphere for visitors.
