Mers El Hadjadj is a town and commune in Oran Province, Algeria. According to the 1998 census it has a population of 14,167. Environment Mars El Hadjadj is located at the extreme east of the Oran wilaya, between the towns of Bethioua in the east and Fornaka (wilaya of Mostaganem). It lies in the Gulf of Arzew, with a harbor protected by two rocky capes. Dunes The area of coastal dunes is limited: to the north by the sea; To the east by the cliff and hill of the marabout of Sidi Mansour; To the south by the national road from Oran to Mostaganem to the bridge of the Macta, then by the river La Macta; To the west by the mouth of this river "(Simonneau and Santa, 1951). This mouth has since been clogged and a new junction with the sea was made through the dune cordon near the bridge of La Macta. "The area of this area is about 180 ha. The vegetation is characterized mainly by the size of the stands of the Ocrea on the coastal dunes and by the extreme variety of the flora on the right bank of the river La Macta. The halophilic and heliophilic species grow there with the littoral species "(Simonneau and Santa, 1951). As the authors have already pointed out, the forest horizon is severely degraded east of these dunes (sparse, mutilated, ...). In October 1983, scientists from the National Agronomic Institute (Algeria), the universities of Liège, Gembloux (Belgium), Nijmegen (Holland), and the Royal Institute of Natural Sciences of Belgium contacted, The Algerian authorities (in particular the Wali of the Wilaya of Mostaganem). Name Called "Port of the Pilgrims" by the Algerians, it is possible that the French name of "Port aux Poules" comes from an erroneous translation due to the phonetic and graphic similarity in Arabic of the words "pilgrims" (ألحجاج), "al-hajāj" and "chickens" (الدجاج) "ad-dajāj". Another hypothesis is an allusion to chickens frequenting the Macta River, behind the dunes of Marsat El Hadjadj. As a third hypothesis, it could simply come from the Roman name of the ancient port which occupied the gulf, whose name was Paulus, named after a high dignitary of the Roman Empire.
