Museo Histórico y Militar de Chile, Military history museum in Santiago, Chile

The Museo Histórico y Militar de Chile is a military museum housed in the Alcázar Building in Santiago, displaying weapons, uniforms, and documents tied to the Chilean armed forces. The rooms are organized across several floors, taking visitors through a broad chronological sequence from the 19th century to more recent periods.

The museum traces its roots to 1895, when President Jorge Montt opened the Museo Militar de Chile; in 1911 it became the military section of the Museo Histórico Nacional. In the 1960s the collection was split, and Colonel Alberto Labbé Troncoso organized a military museum at the Escuela Militar in 1969. The Alcázar Building, a former Escuela Militar (1901–1958) and Escuela de Suboficiales (1967–1995), was declared a Historic Monument on 25 October 1990, and the museum opened there on 25 November 1997.

The museum's name and mission tie it to the Army's own traditions: it was created to spread knowledge of Chile's military history and the institution's values. Its 20 rooms are grouped in three stages, from the Inca presence and the Conquest (1460) to the Cold War, and a memorial honours the roughly 3,000 Chilean combatants who fell in the War of the Pacific.

The museum is easy to reach from the Parque O'Higgins metro station, which is a short walk away. Entry is free, so no advance booking is needed.

The museum holds a specialized library of around 25,000 volumes on military history that is open to researchers and curious visitors alike. A mobile app also offers virtual tours of the collection, letting people explore the objects at their own pace from anywhere.
