Nezar AlSayyad, a Professor of Architecture and the Chair of Cal's Center for Middle Eastern Studies, talks about the design of Tahrir square:
Twenty-three streets lead to different parts of it, which is why it was so successful with the demonstrators. There isn’t one big boulevard that you can block off, and there are two bridges that lead to it as well. One of them saw a clash between the regime and the demonstrators. It’s also the case that all of downtown Cairo, which isn’t that big, has a street that leads to [one] side or another of Tahrir Square.
