Todos-os-Santos Bay (Bahia) — History, geography and conservation

Todos-os-Santos Bay, situated in the state of Bahia, is Brazil’s largest bay and an important ecosystem and historical centre. Its area is commonly cited as approximately 1,223 km² (some sources mention 1,233 km²) and it has an average depth of approximately 9.8 m, with depths reaching 42 m. Diving visibility is generally reported as between 10 and 20 m, a figure used by tour guides as a reference.

History

The bay was named on 1 November 1501 (All Saints’ Day), when a Portuguese expedition led by Gaspar de Lemos, with the participation of Amerigo Vespucci, mapped the region. The practice of naming geographical features after the saint of the day was common at the time.

Its wide and deep inlet attracted sailors, pirates and colonisers as it offered a good anchorage, natural defences, waters rich in fish and fertile land. These characteristics influenced Tomé de Sousa’s choice of the region, on the orders of the King of Portugal, for the founding of Salvador, Brazil’s first colonial capital.

During the colonial period, the bay was one of the main ports in the South Atlantic for the export of products such as sugar and for the shipment of metals, as well as being an important point of arrival for people brought from Africa as slaves. It is recommended to avoid absolute superlatives without specific quantitative historical reference.

Geographical features

Todos os Santos Bay comprises three main sub-bays:

  • Itaparica Bay — formed by the extensive Itaparica Island and the western coastline;
  • São Francisco Bay — with deltaic features and several islands, including Ilha dos Frades;
  • Salvador Bay — the eastern section, which is deeper and navigable by vessels with greater draught, and which borders the state capital.

Many stretches of the shoreline are shallow and covered by mangroves. The main river flowing into the bay is the Paraguaçu, approximately 500–520 km long according to various sources, originating in the Chapada Diamantina region.

Islands, municipalities and environmental protection

The bay is home to several islands (Itaparica, Ilha dos Frades, amongst others) and has been designated an environmental protection area. State Decree No. 7,595, of 5 June 1999, established the Baía de Todos-os-Santos Environmental Protection Area (APA), covering the waters and islands and setting out conservation and management measures.

The APA includes municipalities such as: Cachoeira, Candeias, Itaparica, Jaguaripe, Madre de Deus, Maragogipe, Salinas da Margarida, Salvador, Santo Amaro, São Francisco do Conde, Saubara, Simões Filho and Vera Cruz.

Use, navigation and culture

The bay serves as a natural route between Salvador and the centres of the Recôncavo, with heavy traffic of local vessels and tourist activities (boat trips, diving). Culturally, the Bay of Todos-os-Santos played a central role in the development of the Recôncavo Baiano and the city of Salvador, contributing to the region’s religious, musical and culinary traditions.
