Paris, France 🇫🇷
Paris is full of surprises, but its most famous icon, the Eiffel Tower, actually changes size with the seasons.
Thanks to thermal expansion, the summer heat causes the tower’s iron structure to expand, making it grow up to 15 centimeters (6 inches) taller than it is in winter. The heat even makes the top tilt slightly away from the sun! It’s just one of those quirky facts that proves the City of Light is always dynamic, alive, and full of wonders.
