The Casa de Tucumán (meaning "House of Tucumán" in Spanish, officially Casa Histórica de la Independencia) is a historic building and museum located in San Miguel de Tucumán, Argentina, built during the colonial times. The Congress of Tucumán worked in this house during the Argentine War of Independence, and issued the Argentine Declaration of Independence on July 9, 1816. It was nationalized decades later, and partially demolished for its poor condition.
