DID YOU HAPPEN TO KNOW THIS ABOUT STONEHENGE ? Some people say that if we were to build it again, we do not have the technology to build it. Well, not so - exactly, as the picture show. Stonehenge is believed to be built in about 2,400 BC. Some think much older. It has been rebuilt several times to look better, and to look more like they think it may have looked like when it was new. It was rebuilt in 1901, 1920, 1940, 1958, and 1963. I personally think if they rebuild it too much, it will start to look "artificial". Nothing that is 4,400 years old, or more, looks perfect.
