There are two stone circles at Stonehenge.

W: The stone circle of Stonehenge is one of the most popular tourist attractions in Great Britain. It is more than four thousand years old, and it is one of the wonders in Great Britain. Some of the countries tourist attractions are older and bigger, but Stonehenge is the most famous. I’ m going to tell you a little bit about the history of this amazing circle. It isn’ t really one circle, it’ s actually two, and they were built at different times. The circle of bigger stones was built first.
M: What about the smaller one in the middle?
W: This circle isn’ t as old as the other one.  The stones are different from the others—they came from a different place—but both circles are ancient. They’ re older than some of the Egyptian pyramids!
M: Those stones are huge! How were they carried here?
W: Nobody really knows, it’ s a mystery. Remember, this was before the wheel was invented, and the biggest stone weighs about forty-five tons—that’ s heavier than eight elephants!
M: Why was Stonehenge built, anyway?
W: Well, that’ s even more mysterious. There are lots of theories. Many people believe it was a giant calendar or a temple.
M: This must be one of the most interesting places in Great Britain! I usually think History is boring but this isn’ t the same as an ordinary lesson. This is the best History lesson I’ ve ever had!
W: Well, there’ re a lot of other stone circles in Great Britain—in fact the biggest one in the world is just forty kilometres away from here, at Avebury. It’ s about the same age as Stonehenge and it’ s as interesting, although it’ s less famous.
M: Can we take some photos?
W: Of course you can. Go ahead.
