Today : - To know everything about the only material that makes up the Tower: puddle iron. By Bertrand Lemoine. Why iron and not steel? You liked this article? Book a ticket. The reason behind the choice of Romanian steel and cast iron was attributed to a gifted Romanian engineer, George Panculescu. Panculescu was renowned the world-over for innovating a new way in railway construction which cut the time spent in the building of railway tracks by a large margin. The cutting-edge innovation soon reached Gustave Eiffel who was still looking for a way of building the tower in record time.
The quick construction of the tower was critical since the tower was required to be ready before the opening of the Universal Exhibition scheduled to be hosted in Paris. Eiffel, in , traveled to visit the Romanian engineer and the two had a lengthy discussion on the new system, with Eiffel also expressing his interest in incorporating the system in the construction of the tower.
Panculescu agreed to be part of the project, and the two decided it would be best if the materials would be manufactured in Romania and shipped to Paris to be assembled. His most popular achievement was the Eiffel Tower. Towering nearly meters tall, and weighing 10, tons, the Eiffel tower stands both as a landmark, recognizable throughout the world as the icon of the city of Paris, and as a monumental example of materials' structure, properties and performance.
The tower is composed of puddling iron, not steel as many of today's buildings. The tower was intended as a temporary structure that was to be removed after 20 years. But as time passed, people no longer wanted to see the tower go. By the time the Exhibition was over, most Parisians were proud of the structure," said Iva Polansky, a Calgary-based novelist and historian at Victorian Paris. Gustave Eiffel was also not keen on seeing his favorite project dismantled, and so he set about making the tower an indispensable tool for the scientific community.
Just days after its opening, Eiffel installed a meteorology laboratory on the third floor of the tower. He invited scientists to use the lab for their studies on everything from gravity to electricity. Ultimately, however, it was the tower's looming height, not its laboratory, that saved it from extinction.
In , the city of Paris renewed Eiffel's concession for the tower because of the structure's usefulness as a wireless telegraph transmitter. The French military used the tower to communicate wirelessly with ships in the Atlantic Ocean and intercept enemy messages during World War I.
The tower is still home to more than antennas, broadcasting both radio and television signals throughout the capital city and beyond. The Eiffel Tower is still the centerpiece of Paris' cityscape. More than 7 million people visit this iconic tower every year, according to the attraction's official website. Since the tower's opening, million people from around the world have enjoyed all that the Eiffel Tower has to offer.
And it has a lot to offer.
