The Eiffel Tower grows six inches taller every summer
0:00 / 0:18The Eiffel Tower can grow as much as 6 inches in summer. This seasonal change happens because sunlight heats the iron structure throughout the warmer months.
How thermal expansion affects the tower
As the metal warms from sun exposure, the tower rises above its usual height. The iron expands in response to the heat, causing the entire structure to grow taller.
The tower returns to normal size
When cooler weather arrives, the iron contracts again. The extra height disappears as the metal cools, leaving the Eiffel Tower back at its usual size. This cycle repeats every year, with the landmark expanding in summer and shrinking back down when temperatures drop.
