Stonehenge
The Stonehenge stone circles are in England. People transported the first stones to this place about 5000 years ago. We don't know a lot about Stonehenge. Who built it? How did they build it? Why did they build it? It's a mystery.
People built Stonehenge with bluestones and sarsen stones. There were about 80 bluestones. They came from mountains 250 kilometers away. They are very heavy – some weigh about 4 metric tons. The sarsen stones are even bigger and heavier. About 4000 years ago, people transported them from 30 kilometers away.
