Ancient people built rock monuments, many of which are still standing. Stonehenge was built in England about 5,000 years ago. Its rocks were arranged in four circles, with 30 large rocks on the outsides, some of which weighed 40 tons! It’s believed that people may have used Stonehenge to predict the seasons.

About 4,500 years ago, the Egyptians used millions of stone blocks to build pyramids as tombs for their kings. Pyramids, of course, are pointed at the top. The Egyptians believed the pointed tombs helped their rulers get to heaven.

The Great Wall of China was built more than 2,000 years ago. The 1,200mile- (1,900-km-) long rock structure was created to keep invaders out of China. Today, tourists take long walks along the top of the winding wall.

On Easter Island, off the coast of Chile, stand giant rock statues with large heads and thick bodies. About 600, measuring up to 60 feet (18 m) tall, were created more than 1,000 years ago. Today only about 100 are left. It’s believed that islanders may have carved them as monuments to their ancestors.
