The Martinelli Building, with 28 floors, is the first skyscraper built in Brazil. Located in São Paulo, it is 105 meters tall. The building was planned in 1922 by the Italian-born entrepreneur, Giuseppe Martinelli. Construction began in 1924, and was completed in 1929. At the time of its opening, it was the tallest building in Latin America, and the largest concrete-framed building in the world. The building was completely remodeled by Mayor Olavo Setúbal from 1975 to 1979.
