Algiers was occupied by the French in 1830. As French and other European settlers moved in, the city became two separate entities within one - the traditional Arab city on the hill and the European city below. In the 1930s, French architect Le Corbusier drew up plans for a redesign of Algiers, of which he said: “Here is the new Algiers. Instead of the leprous sore which had sullied the gulf and the slopes of the Sael, here stands architecture…architecture is the masterly, correct, and magnificent play of shapes in the light.” His plan was never implemented, but Brian Ackley has written an interesting article about the plans, entitled Blocking the Casbah: Le Corbusier’s Algerian Fantasy.
On March 26, 1962, at the end of the Algerian War, the street shown above became the scene of bloody riots when French soldiers opened fire on French colonists demonstrating against the French government. So many atrocities took place during the Algerian War.
