calder sculpture mountains and clouds restored 1234774418

Alexander Calder’s monumental sculpture "Mountains and Clouds," located in the Hart Senate Office Building in Washington, D.C., is finally undergoing a full restoration. The 75-foot-wide "clouds" component of the mobile was dismantled in 2016 due to structural safety concerns, leaving only the stationary "mountains" portion on display for nearly a decade. Supported by private funding secured by the Calder Foundation, the project will refabricate the suspended elements and reinstall the computer-controlled motor system that allows the sculpture to rotate.
