All the Great Walls

Border Wall

With all the talk of building a wall between the United States of America and Mexico maybe it is proper to take a look at all the Great Walls of history; because despite all the critics who say walls are divisive or counter productive, walls in history were built to preserve and protect a culture from destruction. Most cities had walls until the invention of gun powder and other explosives made it pointless since walls could easily be breached. Perhaps this is what will happen to the U.S.-Mexico wall which will in turn require laws as what will happen to someone who attempts to destroy parts of the wall. Since, presumably the entire wall will be built within the U.S. so that both sides of the wall will be within the U.S., a person attacking the wall would be doing so by attacking U.S. territory. Could they be tried as terrorists?

Here is a list of the more famous walls of history. The walls in this list do not protect cities as much as entire regions. The list is in no particular order except perhaps common reference.
