The Carthaginian navigator Hanno visited and established a trading post in the area in the 5th century BC, and Phoenician artifacts have been found on the island. bay, by Théodore Cornut, 1767. Around the end of the 1st century BC or early 1st century AD, Juba II established a Tyrian purple factory, processing the murex and purpura shells found in the intertidalrocks at Essaouira and the Iles Purpuraires. This dye colored the purple stripe in Imperial RomanSenatorial togas. Roman merchants settled in the island under Augustus creating a small village: a Roman house with foundations, and also artifacts and coins, were also found on the island. Mogador and the nearby Iles Purpuraires were tied to Mauretania Tingitana by merchant ships in the first and second centuries of the Roman Empire. Some historians think that from Mogador Island the Roman merchants reached the Cape Verde islands and possibly went south until the Gulf of Guinea. Indeed, according to Roman Pliny the Elder, an expedition of Mauretanians sent by Juba II to the Canary archipelago visited the Cape Verde islands: when King Juba II dispatched a contingent to re-open the dye production facility at Mogador in the early 1st century AD, Juba's naval force was subsequently sent on an exploration of the Canary Islands, Madeira and probably the Cape Verde islands, using Mogador as their mission base. After the fall of the Roman empire the commerce from Mogador Island practically disappeared and the island lost most of its importance during the Middle Ages. In 1844, the French Navy besieged the island, and it fell to the French in France's brutal Bombardment of Mogador. In May of 1898, the Sultan's grand vizier negotiated to use the island as a quarantine center for "native Arabs" who were returning from the Hajj and might be carrying any number of diseases prevalent in the world at that time. It has now been designated as a nature reserve, and it cannot be visited without an official authorization. The island has been designated as a protected Ramsar site since 2005.
Flora and fauna
A survey of falcons on the island in 2014 found evidence of Eleonora's falcon crippling and imprisoning live prey for later use. Abdeljebbar Qninba of Mohammed V University, Rabat, and colleagues, found small birds with missing flight and tail feathers trapped, or hiding in small holes or cavities. It is thought either the falcons plucked feathers to keep the birds as a food source for later, or alternatively, the prey are escaping from the falcons by finding refuge in nearby holes.
