Stonehenge is one of the greatest unexplained mysteries of the world. It's certainly no hoax (estimated to be more than 5,000 years old) and is probably the most important prehistoric monument in the whole of Britain.
When you visit Stonehenge, you'll find yourself driving for miles through rolling hills and countryside until, suddenly, you catch sight of this bizarre structure. There's an eerie feel to the area around Stonehenge, and for thousands of years it has soon silently, giving away few clues as to the meaning of its existence.
