At the beginning of the 16th century, a Portuguese squadron of 13 ships crisscrossed the Indian Ocean; One of these ships went adrift, and its captain, Diogo Dias, was therefore the first European to discover the island on August 10, 1500, which he named Isle of Saint Lawrence. In February 1506, Admiral Fernão Soares recognized the place and so Antomabokala, former capital of Ankarana, acquired its name of Diego Suarez, which comes from the junction of the first name of the captain and the surname of the Admiral. In 1635, the bay was mentioned for the first time under this name by the French pilot Berthelot, author of an oriental map of Africa and Madagascar. In 1824, the bay was explored by the English hydrographer Owen, then in 1833, Captain Bigeault, commandant of La Nièvre, traveled the North East coast to carry out hydrographic surveys.
