埃菲尔铁塔的意义？

埃菲尔铁塔在巴黎市中心塞纳河南岸，是世界上第一座钢铁结构的高塔，被视为巴黎的象征。因法国著名建筑师斯塔夫·埃菲尔设计建造而得名。建于1887—1889年。塔高300余米，塔身重达9，000吨，分三层。第一层平台距地面57米，设商店和餐厅；第二层平台高115米，设有咖啡馆；第三层平台高达276米，供游人远眺，底部面积1万平方米，在第三层处建筑结构猛然收缩，直指苍穹。从一侧望去，象倒写的字母“Y”。该塔由1．8万余个组成部件和250多万个铆钉构成。有电梯或徒步登塔顶。入夜，塔顶发出转动着彩色探照灯光，防飞机碰撞。塔旁竖立长方形白色大理石柱，柱顶安放斯塔夫埃菲尔镀金头像。

The Eiffel Tower was built for the International Exhibition of Paris of 1889 commemorating the centenary of the French Revolution. The Prince of Wales, later King Edward VII of England, opened the tower. Of the 700 proposals submitted in a design competition, Gustave Eiffel's was unanimously chosen. However it was not accepted by all at first, and a petition of 300 names - including those of Maupassant, Emile Zola, Charles Garnier (architect of the Opéra Garnier), and Dumas the Younger - protested its construction.

At 300 meters (320.75 m including antenna), and 7,000 tons, it was the world's tallest building until 1930. Other statistics include:

2.5 million rivets

300 steel workers, and 2 years (1887-1889) to construct it.

Sway of at most 12 cm in high winds.

Height varies up to 15 cm depending on temperature.

15,000 iron pieces (excluding rivets). 40 tons of paint. 1652 steps to the top.

In 1889, Gustave Eiffel began to fit the peak of the tower as an observation station to measure the speed of wind. He also encouraged several scientific experiments including Foucault's giant pendulum, a mercury barometer and the first experiment of radio transmission. In 1898, Eugene Ducretet at the Pantheon, received signals from the tower.
