The Big Sweep, a whimsical creation of Claes Oldenburg and Coosje Van Bruggen is located just outside the Hamilton Building, below the museum’s prow that stretches across the avenue. This 35-foot-tall broom and dustpan was inspired by the vastness, climate and topography of the Colorado plains and mountains, as well as by the dazzling light and cleanliness of Denver itself. Big Sweep was completed in 2004 and was shipped in pieces to Denver from the artists’ studio in California.
