The Museo Cabeza de Juárez was constructed in 1976. This museum in Colonia Agua Prieta is an enormous multicolored monument of Benito Juárez’s head that measures in height and weighs six tons. It was decorated by David Alfaro Siqueiros but he died before he could finish the work. His brother-in-law, Luis Arenal Bastar completed it. The work is considered to be a fusion of painting, sculpting, engineering and architecture. Today, it contains a number of abstract murals, a permanent collection of lithographs and a large auditorium. The monument is a symbol of the eastern part of the city.
