Museu Militar

A former 17th-century weapons factory provides an appropriate setting for the Military Museum. The tour begins upstairs, with two rooms devoted to the Napoleonic invasions, and a display on World War I (the Portuguese suffered heavy losses in the 1918 Battle of Le Lys, known to the British as Estaires). A series of rooms with elaborately carved and gilded decoration leads to a comprehensive display of Portuguese arms up to the 20th century. Downstairs you'll find a plethora of cannons and a mind-boggling variety of weaponry captured from adversaries during the colonial wars of the 1960s and '70s. Labels are in Portuguese, but there's a leaflet in English.
