In this engaging and endearing short, director Odette Makhlouf Mouarkech locates a seemingly impersonal structure that became the anchor of a community. The wall of the film’s title is steel-reinforced poured concrete; during wartime it protected its building’s inhabitants from shelling. Through casual but intimate interviews with the individuals who remember the wall as a safe haven, Mouarkech paints a fond and amusing portrait of a group of people who became a sort of family, creating intense camaraderie out of disaster.
