136 years ago today, on March 31, 1889 (March 1, 1889 in the lunar calendar), the Eiffel Tower was completed. Night View of the Eiffel Tower The Eiffel Tower is one of the symbols of Paris and is loved by the French as the "Iron Lady". Together with the Empire State Building in New York and the TV Tower in Tokyo, it is known as the three most famous buildings in the West. In 1889, the 100th anniversary of the French Revolution, Paris held a large international expo to celebrate. The most eye-catching exhibit at the expo is the Eiffel Tower. It became a symbol of the Industrial Revolution that swept the world at that time. The designer of the Eiffel Tower was French architect Gustave Eiffel. In his early years, he was famous as an expert on Hanqiao. In his life, he has many masterpieces that are spread all over the world, but what makes him famous all over the world is this iron tower named after him. In his own words: The Eiffel Tower "drowned me, as if I had only built her all my life." At the beginning, although the French government decided to build the world's tallest tower in Paris, the funds provided were only 1/5 of the cost required. In order to realize his design, Eiffel mortgaged his construction and engineering company and all his property to a bank as investment in the project. On January 28, 1887, construction of the Eiffel Tower was officially started. 250 workers worked 8 hours a day in winter and 13 hours a day in summer. Finally, on March 31, 1889, this steel tower was completed. The Eiffel Tower has more than 18,000 metal parts weighing 7000 tons. During construction, a total of 7 million holes were drilled and 2.5 million rivets were used. Since every component on the tower is strictly numbered in advance, no mistakes were made during assembly. The construction was carried out completely in accordance with the design and no changes were made in the middle, which shows that the design is reasonable and the calculation is accurate. According to statistics, there are more than 5300 design sketches for the tower alone, including 1700 full drawings. The completed Eiffel Tower was 300 meters high and was the tallest building in the world until 1930. Today, radio and television antennas have been added to the tower, and its total height has reached 320 meters. Standing on the tower, the whole of Paris is at your feet. Tourists from all over the world come to visit every day. By 1988, the "Iron Lady" had welcomed 123 million tourists from five continents. On March 31, 1989, the Eiffel Tower was 100 years old. To this end, the Paris Tower Management Company specially hosted a grand commemorative event, recreating the historical scene where Eiffel led the crowd to the summit a century ago: "Eiffel" dressed in a black dress, wearing a wide-brimmed hat, and holding the national flag, and 30 "famous people","construction workers" climbed the stairs amidst the grand sound of drum music. When he planted the tricolour flag on the top of the tower, 21-gun salutes sounded in unison, pigeons flew around the tower, and colorful balloons floated into the blue sky. Hanging on the fence of the second floor platform of the tower is a colorful banner reading "Celebrating the Tower's 100 Years Old" written in the languages of various countries around the world. Countless tourists looked forward to witness this spectacular scene. The Eiffel Tower has gone through a century of ups and downs, but it still stands tall on the banks of the Seine after undergoing major repairs in the early 1980s. It is the pride of all French people. Eiffel Tower Night View Eiffel Tower Night View Eiffel Tower Eiffel Tower
