  5. INTRODUCTION The statue of liberty was presented to the United states by the people of France in 1886.The statue is of a robed woman holding a lit flame, and is made of a sheeting of pure copper, hung on a framework of steel (originally puddled iron) with the exception of the flame of the torch, which is coated in gold leaf (originally made of copper and later altered to hold glass panes.) It stands atop a rectangular stonework pedestal with a foundation in the shape of an irregular eleven-pointed star. The statue is 151 ft (46 m) tall, but with the pedestal and foundation, it is 305 ft (93 m) tall.

  6. SYMBOLISM • The classical appearance (Roman stola, sandals, facial expression) derives from Libertas, ancient Rome's goddess of freedom from slavery, oppression, and tyranny. Her raised right foot is on the move. This symbol of Liberty and Freedom is not standing still or at attention in the harbor, she is moving forward, as her left foot tramples broken shackles at her feet, in symbolism of the United States' wish to be free from oppression and tyranny.[3] The seven spikes on the crown represent the Seven Seas and seven continents.[4] Her torch signifies enlightenment. The tablet in her hand represents knowledge and shows the date of the nation's birth, July 4, 1776.

  7. PHYSICAL CHARACTERISTICS • The interior of the statue used to be open to visitors. They arrived by ferry and could climb the circular single-file stairs (limited by the available space) inside the metallic statue, exposed to the sun out in the harbor (the interior reaching extreme temperatures, particularly in summer months), and about 30 people at a time could fit up into the crown. This provided a broad view of New York Harbor (it faces the ocean) through 25 windows, the largest approximately 18" (46 cm) in height. The view did not, therefore, include the skyline of New York City. The wait outside regularly exceeded 3 hours, excluding the wait for ferries and ferry tickets.


  9. INTRODUCTION • Named after its designer, engineer Gustave Eiffel, the Eiffel Tower is the tallest building in Paris and one of the most recognized structures in the world. More than 200,000,000 have visited the tower since its construction in 1889, including 6,719,200  in 2006, making it the most visited paid monument in the world.Including the 24 m (79 ft) antenna, the structure is 325 m (1,063 ft) high (since 2000), which is equivalent to about 81 levels in a conventional building.

  10. HISTORY • The structure was built between 1887 and 1889 as the entrance arch for the Exposition Universelle, a World's Fair marking the centennial celebration of the French Revolution. Eiffel originally planned to build the tower in Barcelona, for the Universal Exposition of 1888, but those responsible at the Barcelona city hall thought it was a strange and expensive construction, which did not fit into the design of the city. However, because Eiffel took safety precautions, including the use of movable stagings, guard-rails and screens, only one man died.

  11. PHYSICAL CHARACTERSTICS • The metal structure of the Eiffel Tower weighs 7,300 tonnes while the entire structure including non-metal components is approximately 10,000 tonnes. Depending on the ambient temperature, the top of the tower may shift away from the sun by up to 18 cm (7 in) because of thermal expansion of the metal on the side facing the sun. The tower also sways 6-7 cm (2-3 in) in the wind.[7] As demonstration of the economy of design, if the 7300 tonnes of the metal structure were melted down it would fill the 125 meter square base to a depth of only 6 cm (2.36 in), assuming a density of the metal to be 7.8 tonnes per cubic meter. The tower has a mass less than the mass of the air contained in a cylinder of the same dimensions,[8] that is 324 meters high and 88.3 meters in radius. The weight of the tower is 10,100 tonnes compared to 10,265 tonnes of air.


  13. INTRODUCTION • The Leaning Tower of Pisa (Italian: Torre pendente di Pisa) or simply The Tower of Pisa (La Torre di Pisa) is the campanile, or freestanding bell tower, of the cathedral of the Italian city of Pisa. It is situated behind the Cathedral and it is the third structure by time in Pisa's Piazza del Duomo (Cathedral Square). Although intended to stand vertically, the tower began leaning to the southeast soon after the onset of construction in 1173 due to a poorly laid foundation and loose substrate that has allowed the foundation to shift direction.

  14. CONSTRUCTION • The tower began to sink after construction progressed to the third floor in 1178. This was due to a mere three-meter foundation, set in weak, unstable subsoil. This means the design was flawed from the beginning. Construction was subsequently halted for almost a century, because the Pisans were almost continually engaged in battles with Genoa, Lucca and Florence. This allowed time for the underlying soil to settle. Otherwise, the tower would almost certainly have toppled. In 1198, clocks were temporarily installed on the third floor of the unfinished construction.

  15. PHYSICAL CHARACTERSTICS • The height of the tower is 55.86 m (183.27 ft) from the ground on the lowest side and 56.70 m (186.02 ft) on the highest side. The width of the walls at the base is 4.09 m (13.42 ft) and at the top 2.48 m (8.14 ft). Its weight is estimated at 14,500 tonnes. The tower has 296 or 294 steps ;the seventh floor has two fewer steps on the north-facing staircase. The tower leans at an angle of 3.97 degrees[1]. This means that the top of the tower is 3.9 meters from where it would stand if the tower were perfectly vertical.[2]


  17. INTRODUCTION • The Great Wall of China is a series of stone and earthen fortifications in China, built, rebuilt, and maintained between the 6th century BC and the 16th century to protect the northern borders of the Chinese Empire during the rule of successive dynasties. Several walls, referred to as the Great Wall of China, were built since the 5th century BC. The most famous is the wall built between 220–200 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

  18. HISTORY • Qin Shi Huang conquered all opposing states and unified China in 221 BC, establishing the Qin Dynasty. Intending to impose centralized rule and prevent the resurgence of feudal lords, he ordered the destruction of the wall sections that divided his empire along the former state borders. To protect the empire against intrusions by the Xiongnu people from the north, he ordered the building of a new wall to connect the remaining fortifications along the empire's new northern frontier. Transporting the large quantity of materials required for construction was difficult, so builders always tried to use local resources. Stones from the mountains were used over mountain ranges, while rammed earth was used for construction in the plains.

  19. CHARACTERSTICS • During the Ming Dynasty, however, bricks were heavily used in many areas of the wall, as were materials such as tiles, lime, and stone. The size and weight of the bricks made them easier to work with than earth and stone, so construction quickened. Additionally, bricks could bear more weight and endure better than rammed earth. Stone can hold under its own weight better than brick, but is more difficult to use. Consequently, stones cut in rectangular shapes were used for the foundation, inner and outer brims, and gateways of the wall. Battlements line the uppermost portion of the vast majority of the wall, with defensive gaps a little over 30 cm (one foot) tall, and about 23 cm (9 inches) wide.


  21. INTRODUCTION • The first historically documented Egyptian pyramid is attributed to the architect Imhotep, who planned what Egyptologists believe to be a tomb for the pharaoh Djozer. Imhotep may have been the first to conceive the notion of stacking mastabas on top of each other — creating an edifice comprised of a number of "steps" that decreased in size towards its apex. The result was the Step Pyramid of Djozer — which was designed to serve as a gigantic stairway by which the soul of the deceased pharaoh could ascend to the heavens. Such was the importance of Imhotep's achievement that he was deified by later Egyptians.

  22. SYMBOLISM • The Egyptians believed the dark area of the night sky around which the stars appear to revolve was the physical gateway into the heavens. One of the narrow shafts that extends from the main burial chamber through the entire body of the Great Pyramid points directly towards the center of this part of the sky. This suggests the pyramid may have been designed to serve as a means to magically launch the deceased pharaoh's soul directly into the abode of the gods.

  23. NUMBER AND LOCATION • The number of pyramid structures in Egypt today is reported by most sources as being between 81 and 112[citation needed], with a majority favouring the higher number. In 1842 Karl Richard Lepsius made a list of pyramids, in which he counted 67, but more have been identified and discovered since his time. The imprecise nature of the count is related to the fact that as many smaller pyramids are in a poor state of preservation and appear as little more than mounds of rubble, they are only now being properly identified and studied by archaeologists. Most are grouped in a number of pyramid fields, the most important of which are listed geographically, from north to south, below.


  25. INTRODUCTION • The Hanging Gardens of Babylon are considered one of the original Seven Wonders of the World. They were built by Nebuchadnezzar II around 600 BC. He is reported to have constructed the gardens to please his wife, Amytis of Media, who longed for the trees and fragrant plants of her homeland. The gardens were destroyed by several earthquakes after the 2nd century BCE. The lush Hanging Gardens are extensively documented by Greek historians such as Strabo and Diodorus Siculus. Through the ages, the location may have been confused with gardens that existed at Nineveh, since tablets from there clearly show gardens. Writings on these tablets describe the possible use of something similar to an Archimedes' screw as a process of raising the water to the required height.

  26. HISTORY • The ancient city of Babylon, under King Nebuchadnezzar II, must have been a wonder to the traveler's eyes. "In addition to its size," wrote Herodotus, a historian in 450 BC, "Babylon surpasses in splendor any city in the known world. Herodotus claimed the outer walls were 56 miles in length, 80 feet thick and 320 feet high. Wide enough, he said, to allow a four-horse chariot to turn. The inner walls were "not so thick as the first, but hardly less strong." Inside the walls were fortresses and temples containing immense statues of solid gold. Rising above the city was the famous Tower of Babel, a temple to the god Marduk, that seemed to reach to the heavens. "

  27. CONTROVERSY • There is some controversy as to whether the Hanging Gardens were an actual creation or a poetic creation due to the lack of documentation of them in the chronicles of Babylonian history. In ancient writings the Hanging Gardens of Babylon were first described by Berossus, a Chaldean priest who lived in the late 4th century BCE. These accounts were later elaborated on by Greek historians.Recent archaeological excavations of the palace in Iraq have uncovered evidence of a building with vaults and a well nearby. However, the location of the palace complex contradicts where Greek historians placed the Hanging Gardens, which was on the banks of the Euphrates River.


  29. INTRODUCTION • The Taj Mahal stands serene and perfect in its garden of cypresses and reflecting pools on the banks of the River Yamuna. Its pure white marble shimmers silvery white in the moonlight,glows softly pink at dawn,and at close of day reflects the fiery tints of the setting sun. The Taj in all its timeless beauty is still the inspiration of poets and painters,writers and photographers. And lovers still meet here in the moonlight in the shadow of the world's most famous monument to love.

  30. HISTORY • Shahjehan built the Taj in memory of Mumtaz Mahal who died giving birth to their 14th child. No cost was spared to make it the most beautiful monument the world had ever seen. White marble and red sandstone,silver and gold,carnelian and jasper,moonstone and jade,lapis lazuli and coral were fashioned by 20,000 skilled workers to make the emperor's dream a reality. It took 22 years to complete - a symbol of eternal love where Shahjehan too lies buried-united at last with his beloved Mumtaz.

  31. DESCRIPTION • On your Taj Mahal travel you would discover the feminine elegance of Taj Mahal in Agra. The main gate of Taj Mahal Delhi symbolises the veil that covers the face of a beautiful woman on her wedding night. The beauty is slowly unraveled as one moves forward. Inside the Taj, the delicate designs on the arch would draw the attention of the viewers. Standing on the banks of the Yamuna, the Taj, one of the seven wonders of the world, overlooks the Agra Fort. Shah Jahan used to view the Taj from the windows of the Agra Fort in his last days when he was imprisoned by his son Aurangazeb
