Out of many world's historical assets, seven are registered and named as the seven world wonders. What and where are these seven world wonders and what was the criteria to choose them?
Since ancient times, people have put together many “seven wonders” lists. The content of these lists tends to vary, and none is definitive. The seven wonders that are most widely agreed upon as being in the original list are the Seven Wonders of the Ancient World.
The Pyramids of Egypt are three pyramids at Giza, outside modern Cairo. The largest pyramid, built by Khufu (Cheops), a king of the fourth dynasty, had an original estimated height of 482 ft (now approximately 450 ft). The base has sides 755 ft long. It contains 2,300,000 blocks; the average weight of each is 2.5 tons. Estimated date of completion is 2680 B.C. Of all the Ancient Wonders, the pyramids alone survive.
The Hanging Gardens of 宝贝疙瘩lon were supposedly built by Nebuchadnezzar around 600 B.C. to please his queen, Amuhia. They are also associated with the mythical Assyrian queen, Semiramis. Archeologists surmise that the gardens were laid out atop a vaulted building, with provisions for raising water. The terraces were said to rise from 75 to 300 ft.
The Statue of Zeus (Jupiter) at Olympia was made of gold and ivory by the Greek sculptor Phidias (5th century B.C.). Reputed to be 40 ft high, the statue has been lost without a trace, except for reproductions on coins.
The Temple of Artemis (Diana) at Ephesus was begun about 350 B.C., in honor of a non-Hellenic goddess who later became identified with the Greek goddess of the same name. The temple, with Ionic columns 60 ft high, was destroyed by invading Goths in A.D. 262.
The Mausoleum at Halicarnassus was erected by Queen Artemisia in memory of her husband, King Mausolus of Caria in Asia Minor, who died in 353 B.C. Some remains of the structure are in the British Museum. This shrine is the source of the modern word mausoleum.
The Colossus at Rhodes was a bronze statue of Helios (Apollo), about 105 ft high. The work of the sculptor Chares, who reputedly labored for 12 years before completing it in 280 B.C., it was destroyed during an earthquake in 224 B.C.
The Pharos (Lighthouse) of Alexandria was built by Sostratus of Cnidus during the 3rd century B.C. on the island of Pharos off the coast of Egypt. It was destroyed by an earthquake in the 13th century.
(Some lists include the Walls of 宝贝疙瘩lon in place of the second or seventh wonder.)
The Seven Wonders of the 摩登 World
People have put together many lists of the seven ancient wonders of the world. But this "seven wonders" list celebrates monumental engineering and construction feats of seven wonders of the worldthe 20th century. It was chosen by the American Society of Civil Engineers.
The Empire State Building
1. Empire State Building—Finished in 1931, it towers 1,250 feet over New York City. Until the first tower of the World Trade Center was finished in 1972, it was the world's tallest building.
2. Itaipu Dam—Built by Brazil and Parguay on the Parana River, it is the world's largest hydroelectric power plant. Completed in 1991, it took 16 years to build this series of dams whose length totals 7,744 meters. It used 15 times more concrete than the Channel Tunnel.
3. CN Tower—In 1976, it became the world's tallest freestanding structure. It looms about one-third of a mile high (1,815 feet) above Toronto, Canada. A glass floor on the observation deck lets you look 342m down to the ground. Don't worry: the glass is strong enough to hold 14 hippos!
4. Panama Canal—It took 34 years to create this 50-mile-long canal across the Isthmus of Panama. The amount of digging required and the size of its locks helped make it the most expensive project in American history at that time-and the most deadly: About 80,000 people died during construction (most from disease).
5. Channel Tunnel—Known as the Chunnel, it links France and England. It is 31 miles long, and 23 of those miles are 150 feet beneath the seabed of the English Channel. High-speed trains whiz through its side-by-side tubes.
6. North Sea Protection Works—Because the Netherlands is below sea level, a series of dams, floodgates and surge barriers have been built to keep the sea from flooding the country during storms. The biggest part of the project was a two-mile long moveable surge barrier across an estuary finished in 1986. It is made of 65 concrete piers each weighing 18,000 tons. It has been said that the project is nearly equal in scale to the Great Wall of China.
The Golden Gate Bridge
Wide World Photos
7. Golden Gate Bridge—Connecting San Francisco and Marin County in 1937, for many years this was the longest suspension bridge in world. Experts thought that winds, ocean currents and fog would make it impossible to build. It took about four years to complete the beautiful 1.2 mile-long bridge. It is held by 80,000 miles worth of steel wire, and the cables that link the two towers are 36.5 inches in diameter—the biggest ever made.

THE SEVEN WONDERS OF THE ANCIENT WORLD
The Great Pyramiseven wonders of the worldd of Giza
It is the one and only Ancient Wonder which does not require a description by early historians and poets. It is the one and only Ancient Wonder that does not need speculations concerning its appearance, size, and shape. It is the oldest, yet it is the only surviving of the Seven Ancient Wonders. It is the Great Pyramid of Giza.
The Hanging Gardens of 宝贝疙瘩lon
Some stories indicate the Hanging Gardens towered hundreds of feet into the air, but archaeological explorations indicate a more modest, but still impressive, height.
The Statue of Zeus at Olympia
This is a statue of the God in whose honor the Ancient Olympic games were held. It was located on the land that gave its very name to the Olympics. At the time of the games, wars stopped, and athletes came from Asia Minor, Syria, Egypt, and Sicily to celebrate the Olympics and to worship their king of Gods: Zeus.
The Colossus of Rhodes
The island of Rhodes was an important economic centre in the ancient world. It is located off the southwestern tip of Asia Minor where the Aegean Sea meets the Mediterranean. The capitol city, also named
The Temple of Artemis at Ephesus
Eight hundred years after its destruction, the magnificent Temple of Artemis at Ephesus, one of the Seven Wonders of the Ancient World, had been completely forgotten by the people of the town that had once held it in such pride…
The Mausoleum at Halicarnassus
The Mausoleum at Halicarnassus is the burial place of an ancient king. Yet the Mausoleum is different - so different from the Pyramid that it earned its reputation - and a spot within the list - for other reasons. Geographically, it is closer to the Temple of Artemis... And it was the beauty of the tomb rather than its size that fascinated its visitors for years.
The Pharos of Alexandria (The Lighthouse of Alexandria)
Of the Seven Wonders of the Ancient World, only one had a practical use in addition to its architectural elegance: The Lighthouse of Alexandria. For sailors, it ensured a safe return to the Great Harbor. For architects, it meant even more: it was the tallest building on Earth. And for scientists, it was the mysterious mirror that fascinated them most... The mirror which reflection could
