After World War II Opened in 1955, the Surveyor Germán Barbato Municipal Planetarium in Montevideo, Uruguay, is the oldest planetarium in Latin America and the southern hemisphere. 

An enormous metallic contraption dominates the auditorium of the Montevideo Planetarium. The Spitz Model B projector is the oldest functioning device of its kind in the world, projecting a map of the night sky onto the dome of the hall that the public has come to see for more than 60 years.
