Can you name the Seven Wonders of the Ancient World? They were built to honor the people and societies that made them, but only one remains--the Great Pyramid at Giza, near Cairo, Egypt. The others are the Hanging Gardens of Babylon (near Baghdad, Iraq), the Statue of Zeus at Olympia (in Greece), the Temple of Artemis at Ephesus (Selcuk, Turkey), the Mausoleum at Halicarnassus (Bodrum, Turkey), the Colossus of Rhodes (in the harbor at Rhodes, Greece), and the Lighthouse of Alexandria (Egypt).

Today there are new man-made wonders around the world. The Empire State Building in New York City was the tallest building in the world when it was completed in May 1931. Nearly 34,000 men worked on the building. The Sydney Opera House in Australia was designed by the Danish architect Joern Utzon and opened in 1973. The Eiffel Tower in Paris, built in 1888, is so well-liked that it has become a symbol of the city.

There are also many natural wonders that have been created by water, wind, and fire. The Great Barrier Reef is the largest living organism on earth. It stretches 1,250 miles (2,012 kilometers) alongside Queensland, Australia. The Grand Canyon in the state of Arizona in the U.S. was created by thousands of years of water from the Colorado River wearing down rock. A great example of the power of water is Niagara Falls. It lies between Canada and the U.S. Six hundred thousand gallons (2,270,600 liters) of water spill over the falls each second.

There are many more new and incredible man-made and natural wonders to discover in the world. We hope you can go out and see some of them for yourself.
