#1 Bahia Nautical Museum (Salvador)
Housed in the Fort Santo Antônio da Barra, Brazil's oldest military structure, the Bahia Nautical Museum showcases Portuguese maritime history through underwater artifacts, vintage navigation tools, and ship models. The adjacent lighthouse, the oldest in South America, offers expansive views of the Baía de Todos os Santos (All Saints Bay). Exhibits also address the slave trade with direct, honest accounts.
