people use to protect from crazy people
It is an awesome tourist spot.
Use communist Chinas official name in public
china built the great wall of china, the grand canal, and many other things that we use today
the Great Wall was mainly built from earth, stones and wood.
Originally the wall was constructed as a barrier against invaders, such as the Manchus, who were upsetting the known world at one period. Today it is a tourist attraction. It is, by the way, one of the very few constructions that can be identified by the unaided eye from the space lab. The Great wall was also used as a way of moving on the Silk Road.
The Great Wall of China no longer serves its original military purpose, but it is a tourist attraction, so in that sense it still has a use.
Much of it is still standing. It is not longer in use as a defense against invasion.
Of course they did!
