context_page_description: The Andradas Fort is a fortification in the Morro do Monduba, at Guarujá, in the state of São Paulo in Brazil.
context_section_description: The fort was designed in 1934. Construction started in 1938 to provide protection of the port during World War II. It was inaugurated on 10 November 1942 as Forte do Monduba - the last fort in Brazil to be inaugurated. It was later renamed as the Andradas Fort after José Bonifácio de Andrada, Antônio Carlos Ribeiro de Andrada Machado e Silva and Martim Francisco Ribeiro de Andrada.
  It housed political prisoners, including Eduardo Collen Leite, during the military dictatorship in the 1960s.
  The fortification was decommissioned in 1972, with the last 32 grenades launched in a training exercise with 8 kilometres (5.0 mi) range on 28 January 1972. The military base continues to operate as support for the Peace Headquarters and the 1st Brazilian Anti-Aircraft Artillery Brigade.
