Ministerio de Defensa del Perú building, Military headquarters in San Borja, Peru.
The Ministry of Defense building is a government structure in San Borja characterized by bold concrete forms and sharp geometric angles. It spans multiple levels with a central administrative tower connected to several outlying wings.
Construction was completed in 1975 under architect Juan Günther Doering and represented a major modernization effort for Peru's military infrastructure during that decade. This period marked significant changes in how the armed forces organized their institutional presence.
The building stands as an example of brutalist architecture in Peru, demonstrating the international influence on South American military construction during the 20th century.
The building is located in a business district of southern Lima and can be reached by public transportation. Visitors should be aware that this is a secured government facility with restricted access to certain areas.
Locals call the complex 'Pentagonito' because its five-sided footprint deliberately mirrors the iconic Pentagon building in the United States. This nickname reflects how Peru's military architecture adopted international models and reinterpreted them in a local context.
