Farol da Barra, located in Salvador, Bahia, is South America's oldest lighthouse, marking the entrance to the Baía de Todos os Santos (All Saints Bay). The first lighthouse was built in 1698 with a whale oil lantern, while the current iconic 22-meter cylindrical structure with black-and-white stripes was inaugurated in 1839. Housed within the historic Santo Antônio da Barra Fort, the site now contains a comprehensive museum featuring underwater archaeological artifacts, navigation instruments, nautical signaling equipment, and vessel miniatures showcasing the geography and culture of All Saints Bay. The lighthouse remains an active aid to navigation while offering visitors stunning panoramic views of the bay and surrounding coastline, making it a major cultural and historical attraction.
