The creation of the original list of the Seven Wonders of the World is commonly attributed to the Greek author Antipater of Sidon. This list is thought to have been decided based on the popularity of the tourist attraction. Since the creation of the original list a new list known as The New Seven Wonders of the World has been created. This list was decided through a group of people in a committee dedicated to maintaining this list. The current list is The Great Wall of China, Machu Picchu, The Colosseum, Chichen Itza, Christ the Redeemer, Petra and The Taj Mahal. Say no to plagiarism.

Get an original essay Gustave Eiffel didn't actually design the Eiffel Tower, it was actually designed by two men named Koechlin and Nougier. Eiffel became interested in the project and bought back the rights to the project, which is why it is known as The Eiffel Tower. The original plans were much more decorative, featuring glass-walled rooms on each floor, stone facings for the supports, and a bulbous tip, among other things. This design was simplified but some features were retained, such as the arches at the bottom which give the Tower its monumental appearance. The Statue of Liberty and the Arc de Triomphe were used as references for its height. The most technically impressive aspect of the Eiffel Tower is its precise curvature, mathematically designed to give it the most efficient air resistance possible. All the wind shear force passes inside the leading edge struts. The lines drawn tangential to each strut with the point of each tangent at the same height, will always intersect at a second point, which is exactly the point through which the flow resulting from the action of the wind passes on that part of the tower support located above the two points in question. Before joining the high pinnacle, the uprights seem to protrude from the ground, in a certain sense shaped by the action of the wind. Assembly of the structural supports began on July 1, 1887. The Eiffel Tower is made up of 18,000 pieces, all held together by thermally assembled rivets. Each rivet required a four-man team to assemble; one to heat the rivet, another to hold it in place, a third to shape the rivet head, and a fourth to hammer it with a mallet. 2,500,000 rivets were used in the construction of the tower. The tower was completed in a record time of 5 months to build the foundation and 21 months to properly construct the tower. Despite a protest signed by leading French artists, the Eiffel Tower was completed and displayed at the 1889 World's Fair where millions of visitors were amazed by its height, as it was the tallest building at 300 meters until the construction of the Chrysler Building in 1930. The Tower was almost demolished in 1909 during World War I, but remained after it was realized that the Tower could be used for radio broadcasts. The rules for the New Seven Wonders of the World nomination state that the work must be man-made and in an acceptable state of preservation, be culturally and artistically valuable, and be universally recognisable. Not only is the Eiffel Tower in immaculate condition, but it will no doubt remain so as it is repainted every seven years to maintain its beautiful appearance and boasts a staff of 500 dedicated to its continued operation. The Eiffel Tower is so culturally impactful and universally known that it has inspired more than 30 replicas and similar architecture around the world. Furthermore, the Tower attracts 7 million tourists a year and has generated 68 million.
