The Atlantic Gulf, in southeastern Brazil, Rio de Janeiro lies on its southwest coast and Niteroi on its Southeast coast. Found in 1502, originally known as the Gulf of Rio de Janeiro. It is about 31 kilometers (19 miles) long and 29 kilometers (18 miles) wide. The entrance is about 1.61 kilometers (1 mile) wide. Papagaio Peak and Santa Cruz are on the East and Sugar Loaf Mountain and Sao Joao are on the west. Fort Laje Island at the mouth of the Bay was the temporary residence of Huguenots in 1555. The Bay is dotted with several islands, including Villegagnon, Governador and Cobras Island, with defences, naval warehouses, hospitals and dry docks. From just north of Rio de Janeiro's central point, a bridge crosses the Bay and connects to Nitroy.
