The Eiffel Tower gets bigger every summer – here’s why.
6 August 2025
The structure known today as the Eiffel Tower was originally dubbed the Tour de 300 mètres, the 300-metre tower. The name was proposed by engineers Maurice Koechlin and Émile Nougier to Gustave Eiffel, who oversaw the tower’s construction.
On hot days, the Eiffel Tower grows by 12-15cm, and leans away from the sun.
