Delta Solar

Delta Solar is a public artwork by the Venezuelan sculptor Alejandro Otero, located in front of the National Air and Space Museum in Washington, D.C. The abstract sculpture consists of stainless-steel sails that sway in the wind, mounted on an open geometric lattice shaped like a delta formation. The piece rests on a concrete base and is surrounded by a reflecting pool. It pays tribute to modern technology as well as to the Inca sun cult. It was dedicated on June 29, 1977, by then Venezuelan President Carlos Andrés Pérez as a gift marking the bicentennial of the American Revolution. The unveiling had originally been planned for spring, but cold weather prevented the pouring of the concrete foundation.
