Trindade and Martim Vaz Archipelago

Trindade e Martim Vaz is a Brazilian archipelago in the Atlantic Ocean, a Federal Territory off the coast of Espírito Santo, about 1,200 kilometres east of Vitória.

It consists of two main islands (Trindade and Martim Vaz), separated by 48 kilometres, with a total area of 10.4 km².

Trindade and Martim Vaz are considered by navigators to be an immense wall in the middle of the Atlantic Ocean and are uninhabited, except for a garrison of 32 Brazilian Navy personnel on Trindade Island.

Discovery and history

During the reign of King Manuel I of Portugal, the island of Martim Vaz was discovered in 1501 by the Galician navigator João da Nova.

About a year later, the Portuguese navigator Estêvão da Gama visited the largest island and named it “Ilha da Trindade”.

The islands remained under Portuguese rule until Brazil’s independence, when they became Brazilian.

In 1890 the United Kingdom occupied Trindade, but the British abandoned the islands in 1896 after an agreement between the two countries, mediated by Portugal.

Martim Vaz Islands

Martim Vaz is a group of islands that includes the main island, Martim Vaz (with a maximum altitude of 175 metres), two steep and inaccessible islets ( Ilha do Norte, with a maximum altitude of 65 metres, and Ilha do Sul, with a maximum altitude of 122 metres), and several smaller rocks, such as Rocedo Agulha.

The Martim Vaz complex covers a total area of 0.3 square kilometres (30 hectares).

The vegetation is mainly undergrowth, with the presence of rare bushes at the top, which are strongly whipped by the wind. The fauna consists only of crabs, endemic spiders and hundreds of migratory birds.

The only less risky way to disembark is by helicopter, due to the vertical and flat topography at the top of the island.

Discovered in 1512 by João da Nova, the island was visited in 1514 by Juan de la Cosa, who named it Santa Maria Esmeralda.

In 1768 the Frenchman La Pérouse tried to climb the rocks, but two of his sailors died in the attempt. In their honour, the name of the archipelago was changed to Martim Vaz.

In 1951, the Brazilian Navy wanted to formally take possession of the islands, and a military garrison attempted to raise the flag on the main island, but the ship sank, resulting in the deaths of 12 sailors.

Island Geology

The island of Trindade has several volcanic centres, with the most recent volcanic activity recorded about 50,000 years ago at the Paredão Volcano.

This volcano produced a pyroclastic flow that formed an ash cone.

The most important plant species is the giant fern, while the yellow crab (Geocarcinus lagostoma, Grapsus grapsus) is the most important terrestrial species, found at high altitudes.
