    with casings of stones to smoothen its surface. It probably is consideredto be one among the seven wonders of world because of its sheer size.

    Location:

    This wonder of the world was located in the east bank of Euphrates, South ofBaghdad in Iraq.

    Description:

    The King Hammurabi is the most famous king of the Babylonian kingdom. The

    whole kingdom flourished under his rule. His son Nebuchadnezzar is the one

    who built the Hanging gardens ofBabylon, one of the Seven wonders of world.

    Nebuchadnezzar ruled the country for 43 years from 605 BC. He constructedimpressive array of temples, palaces and streets. It is being told that he built this

    garden to please his wife, Amyitis. Amyitis, daughter of the king Medes seems to

    have had a passion for mountainous surroundings. There are some other

    accounts which say that this wonder of the world was actually built by the

    Assyrian Queen Semiramis.

    The ancient accounts of this hanging gardens (one of the seven wonders of the

    world) describes the structure to be a stairs like one. The Greek geographer

    Strabo, describes it as , "the garden consists of vaulted terraces raised one

    above another, and resting upon cube-shaped pillars. These are hollow and filled

    with earth to allow trees of the largest size to be planted. The pillars, the vaults,

    and terraces are constructed of baked brick and asphalt."

    The irrigation system was supposedly the complex part built on this gardens.

    This region had very scarce rains. Slaves were used to push the water upwards

    using some ancient method of irrigation. Of course there must be some

    exploitation of slave labor to maintain one among the seven wonders of the

    world. The gardens did not really hang on the roof using cables or ropes. But this

    name from the sense that it was built on the roof top. Some accounts state that

    the gardens are 400 by 400 feet and 80 feet high.

    During the 5th century, they decided to have a temple for their king of gods and

    Libon was assigned the task of completing the work. Libon designed the templeand Pheidias was asked to build a big statue for Zeus. Pheidias had good

    techniques with him to build big statues. He used wooden frame to make the

    outer casings for the statues in gold. His workshop still remains and incidentally

    its size can accommodate building of such big statues. He built a statue of

    approximately 40 ft height.

    The statue was so high that, even while sitting the head of the god Zeus was

    near the roof of the temple. This is what amazed the historians and poets of

    those times. This simply illustrates that the god Zeus is so big that even if he

    stands, the whole roof would come off its place. Zeus was seated on a throne,

    draped in gold robe. Zeus had a wreath around his head and held a figure of hismessenger in his right hand.

    The statue, one among the seven wonders of world was occasionally presented

    with gifts from rulers. The most notable one was the woolen curtain dedicated

    by the Syrian king.

    In the I century AD, Roman emperor Caligula tried to take the statue to Rome

    but failed. But before 5th century AD, wealthy Greeks have moved it toConstantinople which saved the statue for some more years. After that a severe

    fire has destroyed the statue. Even before this the temple site was ravaged by

    floods, landslides and earthquakes to the extent that the structure was badly

    damaged. Now the remnants of this statue, one among the seven wonders of

    world have gone without even a small trace except for the reproduction in some

    of the medieval coins.

    world. It is located off the southwestern tip of Asia Minor where theAegean Sea meets the Mediterranean. The capitol city, also namedRhodes, was built in 408 B.C

    If this wonder were remaining, this would have been one of the tallest

    artifacts in the world. This wonder of the world was erected tocommemorate the victory of Rhodians against the Antagonids.

    Antagonids in 305 BC, wanted to break their alliance and tried invading Rhodes andfound this city to be impenetrable. Antagonids were fighting for almost one full year. By

    this time the support for Rhodes have started coming in from Egypt. So Antagonids

    started withdrawing their forces and fled, leaving behind lots of their arms and

    ammunitions, which lead to the construction of one of the seven wonders of world.

    Rhodians sold some of those equipments and to celebrate their victory, erected a statue

    for their Sun God, Helios. Lot of the metals used in this construction came from the leftoff belongings of Antagonids. This is the Colossus of Rhodes, one of the seven wonders of

    world.

    The construction took 12 years and the stature was erected in 282 BC. During the

    earthquake at about 226 BC, this Colossus of Rhodes (statue) was damaged and fell

    down. When they planned to rebuild it, the idea was dropped because some Oracle saidthe city will face misfortune if this statue is rebuilt. That was the final chapter to the story

    of this wonder of the world.

    was visited by lots of merchants, tourists, artisans, kings to pay their homage and

    share their profits with the Artemis goddess. Lots of scholars venerated to the

    Introduction:Introduction:

    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 This is such an elegant piece ofarchitectural wonder that, it found a place in the list of ancient wonders among

    the great seven wonders of the world, like pyramids.

    LocationLocation::

    This Wonder of the World, is located in the city of Bodrum, on the Aegan sea, in

    south-west Turkey. This is actually closer to the ancient Temple of Artemis.

    Introduction:Introduction: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 be seen

    more than 50 km (35 miles) off-shore.

    The mirror which was mounted on this lighthouse could reflect the light more

    than 35 miles off-shore. Of the 6 ancient destroyed wonders, this was the last tobe destroyed around 1480 AD.

    LocationLocation::On the ancient island of Pharos, now a promontory on the harbor of the city ofAlexandria in Egypt.

    Description:Description:

    This lighthouse was built around 280 BC and was around 134 m in height. Thiswas built in the city of Alexandria.The light house had a good mirror which can reflect the sun light to a very longdistance. Mythical stories used to say that this mirror was used to burn theenemy ships.

    The Macedonian conqueror, Alexander during his successful reign, had tried

    establishing approximately 17 cities in the name of Alexandria. The only onesurvived long was the one in Egypt. That too even this city was not completelybuilt by Alexander. The completion of the construction of this city wasachieved by his commander Ptolemy I Soter.

    Ptolemy connected Alexandria to the Pharos island by a bridge. It was realized that the

    sailing in this coastal region is very dangerous. That is why he decided to build a light

    house. This project was initiated during Ptolemy's reign in 290 BC and completed after

    his death by his son Ptolemy Philadelphus. Sostratus who lived in the same time as

    Euclid, was the architect. This used to remain in the harbor for centuries. This wonder of

    the world also depicted in the Roman coins that time.

    The writings of the Arab conquerors are very good source of information about thislighthouse. The new rulers moved the capital to the Cairo. So this place had lost its

    importance. Three earthquakes stuck in various periods (around AD 956, AD 1303 and AD

    1323 ) have damaged the lighthouse significantly. The during AD 1480 the Egyptian

    Mamelouk Sultan, has built a medieval fort at the same place. That was the end to the

    story of the light house.

    This lighthouse was so popular that the word Pharos came into French, Spanish and

    Italian to mean lighthouse.

    beyond. About 20,000 workman were employed daily to complete the complex at the

    expense of 40,000,000 rupees.

    The whole Taj complex was conceived as an entity because Mughal building architecture

    allowed no amendment in them. The mosque and Jawab of the Red Sikiri sand stone and

    some pietra duta (hard stone )surface decoration ,contrast in color and texture with the

    mausoleum of pure white marble. The mausoleum stands on a marble plinth 23 feet high

    in India with Persian features that had been seen in the Humayun tomb at Delhi,

    began in 1564. The Taj Mahal has won a good praise virtually from the time of

    The Great Wall of China, or "The long wall of 10,000 Li, is a series of stone and earthen

    fortifications in China, built, rebuilt, and maintained between the 5th century BC and the

    16th century to protect the northern borders of the Chinese Empire from Xiongnu attacksduring the rule of successive dynasties. Several walls, referred to as the Great Wall of

    China, were built since the 5th century BC. One of the most famous is the wall built

    between 220206 BC by the first Emperor of China, Qin Shi Huang; little of it remains; it

    was much farther north than the current wall, which was built during the Ming Dynasty.

    The Great Wall stretches over approximately 6,400 km (4,000 miles) from Shanhaiguan in

    the east to Lop Nur in the west, along an arc that roughly delineates the southern edge of

    Inner Mongolia, but stretches to over 6,700 km (4,160 miles) in total more recent

    archaeological survey using advanced technologies points out that the entire Great Wall,

    with all of its branches, stretches for 8,851.8 km (5,500.3 mi). At its peak, the Ming Wall

    was guarded by more than one million men. It has been estimated that somewhere in therange of 2 to 3 million Chinese died as part of the centuries-long project of building the

    wall.

    In the 15th century, the Incan Emperor Pachactec built a city in the clouds on the

    mountain known as Machu Picchu (old mountain). This extraordinary settlement lieshalfway up the Andes Plateau, deep in the Amazon jungle and above the Urubamba River.

    It was probably abandoned by the Incas because of a smallpox outbreak and, after the

    Spanish defeated the Incan Empire, the city remained lost for over three centuries. It was

    rediscovered by Hiram Bingham in 1911.

    Chichn Itz, the most famous Mayan temple city, served as the political and economiccenter of the Mayan civilization. Its various structures the pyramid of Kukulkan, the

    Temple of Chac Mool, the Hall of the Thousand Pillars, and the Playing Field of the

    Prisoners can still be seen today and are demonstrative of an extraordinary commitment

    to architectural space and composition. The pyramid itself was the last, and arguably the

    greatest, of all Mayan temples.

    Mount Everest is the highest mountain on Earth, as measured by the height above sea levelof its summit, 8,848 metres (29,029 ft). The mountain, which is part of the Himalaya

    range in High Asia, is located on the border between Sagarmatha Zone, Nepal, and Tibet,

    China.

    In 1856, the Great Trigonometric Survey of India established the first published height of

    Everest at 29,002 ft (8,840 m), although at the time Everest was known as Peak XV. In

    1865, Everest was given its official English name by the Royal Geographical Society uponrecommendation of Andrew Waugh, the British Surveyor General of India at the time.

    Waugh was unable to propose an established local name because Nepal and Tibet were

    closed to foreigners at the time, although Chomolungma had been in common use by

    Tibetans for centuries.

    The Victoria Falls or Mosi-oa-Tunya (the Smoke that Thunders) is a waterfall situated in

    southern Africa on the Zambezi River between the countries of Zambia and Zimbabwe.

    The falls are some of the largest in the world.

    Victoria Falls was so named by Scottish explorer David Livingstone (see pre-colonial

    Mosi-oa-Tunya is the name in official use in Zambia. The World Heritage List recognises

    both names.[1] While it is neither the highest nor the widest waterfall in the world, it isclaimed to be the largest. This claim is based on a width of 1.7 kilometers (1 mi) and

    height of 108 meters (360 ft), forming the largest sheet of falling water in the world. The

    falls' maximum flow rate compares well with that of other major waterfalls.

    The Grand Canyon is a steep-sided gorge carved by the Colorado River in the United

    States in the state of Arizona. It is largely contained within the Grand Canyon NationalPark one of the first national parks in the United States. President Theodore Roosevelt

    was a major proponent of preservation of the Grand Canyon area, and visited it on

    numerous occasions to hunt and enjoy the scenery.

    Longstanding scientific consensus has been that the canyon was created by the Colorado

    River over a six million year period. The canyon is 277 miles (446 km) long, ranges in

    width from 4 to 18 miles (6.4 to 29 km) and attains a depth of over a mile (1.83 km)

    (6000 feet). Nearly two billion years of the Earth's geological history have been exposed as

    the Colorado River and its tributaries cut their channels through layer after layer of rock

    while the Colorado Plateau was uplifted. The "canyon began in the west, followed by

    another that formed in the east. Eventually, the two broke through and met as a single

    majestic rent in the earth some six million years ago. [...] The merger apparently occurredwhere the river today bends to the west, in the area known as the Kaibab Arch."

    The Great Barrier Reef

    This is the only living organism large enough to be seen from space. It stretches 1,200miles off of the coast of Queensland, Australia. Amongst the reef, there are hundreds of

    smaller islands ripe for exploring. This is the largest marine preserve in the

    world. Naturally, it is hoe to a plethora of 500 species of beautifully colored coral, 4,000

    kinds of shellfish, 1,500 different fish species.

    This reef is perfect for water sports, including sailing, snokeling, and diving. You can find a

    travel agency or guides who are willing to help you out on the reef almost anywhere on the

    northwest coast of Australia. If you are not into the diving, there is an underwater

    observatory where you can see all the wonderful underwater biodiversity.

    The best time to travel here is from October to November for the best ocean waterconditions. The clear waters and beauty of the reef is absolutely stunning, and as global

    warming and changes in climate destroy reefs everywhere, we should try to visit,

    appreciate, and protect this valuable and unique ecosystem.

    Auroras, sometimes called the northern and southern (polar) lights or aurorae (singular:

    aurora), are natural light displays in the sky, usually observed at night, particularly in the

    polar regions. They typically occur in the ionosphere. They are also referred to as polar

    auroras. In northern latitudes, the effect is known as the aurora borealis, named after the

    Roman goddess of dawn, Aurora, and the Greek name for north wind, Boreas by Pierre

    Gassendi in 1621.

    The aurora borealis is also called the northern polar lights, as it is only visible in the sky

    from the Northern Hemisphere, the chance of visibility increasing with proximity to theNorth Magnetic Pole, which is currently in the arctic islands of northern Canada. Aurorae

    seen near the magnetic pole may be high overhead, but from further away, they illuminate

    the northern horizon as a greenish glow or sometimes a faint red, as if the sun was rising

    from an unusual direction. The aurora borealis most often occurs from September to

    October and from March to April. The northern lights have had a number of names

    throughout history. The Cree people call this phenomenon the "Dance of the Spirits."

    Aurorae can be spotted throughout the world. It is most visible closer to the poles due to

    the longer periods of darkness and the magnetic field.
