Did you know that the Eiffel Tower is about 15 cm shorter in the winter than in the summer?

Steel expands slightly when it gets warmer. In winter, at -10°C, the Eiffel Tower contracts and is about 15 cm shorter than in summer, when it’s 20°C. Another effect of heat is the “bending” of the Eiffel Tower. Due to the complex steel lattice construction which is both flexible and lightweight, This complex arrangement of metal beams allows the tower to absorb and distribute temperature-induced stresses more effectively, leading to noticeable bending. As a result, the Eiffel Tower can bend visibly by about 18 cm.

This bending is a normal consequence of the thermal expansion and contraction of the steel, and the design of the tower accounts for these changes to ensure stability and safety.
