Eiffel Tower

The tower was constructed to serve as the grand centerpiece and entrance arch for the 1889 Exposition Universelle, also known as the World's Fair. It was specifically built to commemorate the 100th anniversary of the French Revolution.

The wrought-iron lattice structure was designed and built by the French civil engineer Gustave Eiffel and his engineering company. Engineers Maurice Koechlin and Émile Nouguier, along with architect Stephen Sauvestre, were also key contributors to the final design.

The tower stands approximately 330 meters, or roughly 1,083 feet tall, which is equivalent to an 81-story building. Its actual height can fluctuate slightly depending on the temperature, as the iron expands in the summer heat.

Visitors who choose to take the stairs will climb exactly 674 steps to reach the second floor of the tower. To get to the absolute summit, visitors must take an elevator from the second floor, as the stairs to the top are closed to the public.
