The Empire State Building in New York in the US is one of the tallest buildings in the world. And it’s also one of the modern wonders. It is 381 metres to the top and has 102 floors.

Much smaller, although thousands of years older, is the Great Pyramid at Giza in Egypt. It was about 146 metres tall when it was first built.

Stonehenge: a man-made wonder of the world

Stonehenge is an ancient circle of stones in the south of England. It is about 5,000 years old. It was probably a place to bury dead people or a place to study the stars and the sky at night.

    There are dozens of stones, and they are different in height. The stones came from about 200 kilometres away. Some of the stones are missing, but it is still one of the most wonderful sights of the world. It is a wonder also because of this question: How did ancient people move these huge stones without machines to help them? No one knows the answer.
