[1] The Portuguese king Dom Manuel ordered Diogo de Azambuja, the founder of Castello da Mina, to build a castle on a small island, now called "La Petite Ile", in the Moroccan locality of Mogador.

[1] The role of the castle was to serve as a relay on their routes along the Moroccan coast, between Safi, where the Portuguese were established since the end of the 15th century, and Agadir, which had just been occupied in 1504.

[1] The construction process was accompanied by constant attacks from the Beni Regraga tribe, strongly motivated by Jihad and supported by the Saadian Sheriffs.

The Castelo Real was totally demolished in the 18th century, following the plans to build the Essaouira city and fortifications by Mohammed ben Abdallah.

Four of them only had a short duration: Graciosa (1489), São João da Mamora (1515), Castelo Real of Mogador (1506–10) and Aguz (1520–25).
