Great Wall?

Whenever any group of people, no matter the reason, embark on a massive project such as the Great Wall, it is a remarkable achievement. I think there is some speculation on whether it was really a complete long wall, but that doesn't matter much to me. I think it is a testament to the ability of man to envision the need, put it into a plan and carry it out.

Well in the time that's made it was great (the king of china tried to protect his kingdom from other people and to start making the life in the cites and town good , so he tried to stop other people from attacking his kingdom to do that , and i am not sure it it been destroyed and been rebuilt again) As i know you can you see the Great Wall from the moon so it's absolutely great when he was build and as it is now! that's in my view :)
