The Eiffel Tower is known to grow taller during the summer months. Made of iron, the tower expands when it absorbs heat, increasing in height by up to 15 centimeters (6 inches). This is due to the physical property of thermal expansion, where materials expand when they are heated. Engineers designed the tower with this in mind, ensuring that the structure can accommodate such changes in size. In cooler months, the iron contracts again, returning to its usual height. This seasonal change highlights the fascinating ways in which large structures respond to temperature fluctuations.

Why Thermal Expansion Matters in Engineering

Thermal expansion is an important consideration in the design of many structures, not just iconic ones like the Eiffel Tower. Bridges, railways, and skyscrapers all need to account for changes in temperature to prevent damage. Engineers incorporate expansion joints into these structures to allow for movement without causing cracks or bends. The Eiffel Tower's ability to grow taller during the heat of summer serves as a visible and impressive example of how temperature can affect the stability and design of major landmarks, showing the importance of considering the environment when building large structures.
