Delta Solar is a public artwork by Venezuelan sculptor Alejandro Otero located outside of the National Air and Space Museum in Washington, DC, United States.[1] Delta Solar is meant to pay homage to modern technology and the Inca sun cult.[2]


This abstract sculpture consists of stainless steel "sails" that move in the breeze. They are attached to an open geometric grid formed into the shape of a Delta Formation.[1] It sits on concrete and in a reflecting pool.[2]


The sculpture was dedicated on June 29, 1977 by Carlos Andrés Pérez, president of Venezuela as a gift celebrating the Bicentennial of the American Revolution.[1] The sculpture was originally supposed to be dedicated in the Spring, however, cold weather prohibited the pouring of concrete for the base of the structure.[3]
