The Mano de Desierto is a large-scale sculpture of a hand located in the Atacama Desert in Chile, 75 km to the south of the city of Antofagasta, on the Panamerican Highway. The nearest point of reference is the “Ciudad Empresarial La Negra” (La Negra Business City). The sculpture was constructed by the Chilean sculptor Mario Irarrázabal at an altitude of 1,100 meters above sea level. Irarrázabal used the human figure to express emotions like injustice, loneliness, sorrow and torture. Its exaggerated size is said to emphasize human vulnerability and helplessness. The work has a base of iron and cement, and stands 11 metres (36 ft) tall. Funded by Corporación Pro Antofagasta, a local booster organization, the sculpture was inaugurated on March 28, 1992.
