In England, Stonehenge stands as a monument to the works of an ancient race of people, but why did they build it?
We don't really know, and the experts are divided.
So, instead, let's talk about Citi-Henge.
That's right, this isn't Stonehenge, it's located in London. This is Citihenge, made with 18 scrap cars, placed in the middle of London near the Tower Bridge and other London landmarks.
It was created by an artist who calls himself Tommy Gunn. Each of three car henges is 15 feet wide and more than 15 feet high and the whole thing weighs about 36 tons.
It was paid for by Skoda, a Czech car maker to promote its new Citigo car. On the basis of this, Mac now believes Stonehenge was really an advertisment for a Druid excavating firm.
