The square is notable as being where many political rallies take place and Fidel Castro and other political figures address Cubans. Fidel Castro has addressed more than a million Cubans on many important occasions, such as 1 May and 26 July each year.
The square is dominated by the José Martí Memorial, which features a 109 m (358 ft) tall tower and an 18 m (59 ft) statue. The National Library, many government ministries, and other buildings are located in and around the Plaza. Located behind the memorial are the closely guarded offices of former President Fidel Castro. Opposite the memorial on the far side of the square is the famous Che Guevara image with his well known slogan of "Hasta la Victoria Siempre" (Until the Everlasting Victory, Always) that identifies the Ministry of the Interior building.
Construction of the square and the José Martí monument commenced during the Presidency of Fulgencio Batista. The square and the memorial were completed in 1959 (the year Fidel Castro came to power). It was originally called Plaza Cívica (Civic Square). After the Cuban Revolution (1959), it was renamed "Plaza de la Revolución" or "Revolution Square." An elevator allows access the top of the memorial, at 109 m one the tallest points in the city.
