How does the Eiffel Tower withstand forces?
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.

What makes a tower strong and stable?
Some general rules about structural stability: the lowest the center of gravity, the more difficult it is to make a structure topple over, therefore the more stable is the structure. It is more difficult to make a structure with a wide base topple over so, the wider the base therefore, the more stable the structure.
