Is the Eiffel Tower strong and stable?

The CETIM's model suggests that the Eiffel Tower will last for at least two or three hundred more years. Simulated precipitation, temperature, and extreme wind conditions are projected to have little effect, and even doubling the weight of the tower, though causing it to “move,” will still leave it safely standing.

Eiffel was one of the first engineers to recognize the importance of wind forces on tall structures. He designed the surface of his Tower to be so minimal that the wind has virtually nothing to grab onto. All pieces of the Tower form an open lattice of light trusses through which the wind can blow.

Nothing remotely like the Eiffel Tower had ever been built; it was twice as high as the dome of St. Peter's in Rome or the Great Pyramid of Giza. In contrast to such older monuments, the tower was erected in only about two years (1887–89), with a small labour force, at slight cost.

The Eiffel Tower is made of puddle iron, a material that could last almost forever if it is repainted regularly. However, several factors pose a threat, including rust, pollution inherent to its location in a big city, bird droppings and the weather.

Visiting time to the Eiffel Tower is not limited. However we recommend that you plan sufficient visiting time at the end of the evening (i.e. around 1 1/2 hours for a visit to the 2nd floor and 1st floor and 2 1/2 hours for a full visit up to the top).

The tower's summit can only be reached via elevator, but its first two levels are accessible through a series of winding staircases inside its pillars — 327 steps to the first level and then 347 to the second (that's 674 total if you're counting). It might sound hard, but climbing the tower is easier than you'd think.

The peak experience is halfway down. By all means, go to the top if you have the time (skip it if your schedule's tight). But I prefer to linger on the second floor: For me, the best views are from this middle level — high enough to see all of Paris, but low enough to pick out distinguishing landmarks.
