History of creation

The tower was erected on the Champ de Mars opposite the Jensky bridge across the River Seine, Branly embankment.

Alexander Gustave Eiffel

- french engineer

The Eiffel Tower is the most recognizable architectural landmark of Paris, internationally known as the symbol of France, named after its designer Gustave Eiffel.

Eiffel himself called it simply - a 300-meter tower.

Height

«La tour Eiffel»

Initially, the Eiffel Tower towered 300.65 m above ground level. The height along with the new antenna is 324 meters.

For over 40 years, the Eiffel Tower was the tallest building in the world, almost 2 times higher than the tallest buildings in the world at that time - the Pyramids of Cheops (146.6 m), Cologne (156 m) and Ulm Cathedral (161 m), while 1930, she was not surpassed by the Chrysler Building in New York.

Color

«La tour Eiffel»

Throughout its history, the tower has repeatedly changed the color of its painting - from yellow to red-brown. In recent decades, the Eiffel Tower has invariably painted in the so-called “brown-eiffel” - an officially patented color close to the natural shade of bronze.

"Iron Lady" resists the destructive effect of time thanks to 57 tons of paint, which must be updated every 7 years.

Eiffel Tower Dimensions

The weight of the metal structure is 7,300 tons (total weight 10,100 tons). Today, three towers could be built from this metal at once. The foundation is removed from concrete masses. The oscillations of the tower during storms do not exceed 15 cm.

The lower floor is a pyramid (129.2 m each side at the base), formed by 4 columns connected at an altitude of 57.63 m by an arch vault; on the vault is the first platform of the Eiffel Tower. The platform is a square (65 m across).

On this platform, the second pyramid-tower rises, which is also formed by 4 columns connected by a vault on which there is (at an altitude of 115.73 m) the second platform (a square of 35 m across).

Nowadays...

The huge iron tower is not particularly affected by the wind. Even the strongest wind that happened in Paris (about 180 km / h) deflected the top of the tower only 12 cm. The Sun has a much greater effect on it. The side facing the sun expands from the heat so that the tip deviates to the side by 18 cm.
