I knew about the U.S.-Mexico, Israel-West Bank, Korea, and Spanish (Melilla-Morocco) walls, but I had not heard of the two longest ones: the Moroccan built wall around Western Sahara, and India's wall to completely encircle Bangladesh. It's amazing how little coverage walls of that size have gotten. All walls fall eventually but in the meantime they make a huge social impact, not always in the way foreseen by their builders. All of these walls are going to have a major effect on the societies by fostering social separation that will last longer than the physical structure.
It's also a little strange that the article doesn't mention the Israel-Gaza wall. I guess the Guardian doesn't want to be seen as picking on Israel too much.
