The Casa Museo Grau is the birthplace and childhood home of Admiral Miguel Grau Seminario, Peru's most celebrated naval commander and the national hero of the 1879 War of the Pacific. The house has been preserved as a museum and filled with period furnishings, personal objects, photographs, and documents related to Grau's life and the war against Chile.
The museum is compact but well-maintained and provides good context for visitors unfamiliar with the War of the Pacific — a conflict that still shapes relations between Peru, Chile, and Bolivia. Grau's story is a genuinely compelling one, and the museum tells it without nationalist bombast. Free entry; open Tuesday to Sunday mornings.
