Intentional communities founded by women for women, all-female communities on a large scale have been the stuff of legend. But now, Saudi Arabia is going to take women-only cities out of the realm of myth and make them a reality. The Saudi Industrial Property Authority (Modon), which is developing the women-only industrial city at Hofuf, said it hoped the city would open next year. Why does Saudi Arabia need to do this? Is it because the restrictions on womens' lives is so extreme? Even if the goal is to create a space where women too can be productive, wouldn't a segregated city never be as productive or creative as one where the free exchange of ideas among diverse converging people is allowed?
