The Eiffel Tower Grows Taller Every Summer And Nobody Told You

Paris has a secret shape-shifting landmark, and the reason is hiding in your school science lessons.

Here is a fact that sounds made up but is completely real: the Eiffel Tower is taller in summer than it is in winter.

The whole thing is built from iron, and metal expands when it heats up. On a blazing hot day, the tower's temperature rises and its structure quietly stretches upward.

The difference can be several centimetres, enough to matter but far too subtle for any tourist to spot with the naked eye. The tower can even lean slightly away from the sun as one side warms faster.

So the postcard-perfect landmark is secretly breathing with the seasons, swelling in the heat and shrinking in the cold. Paris has a monument that never quite stays the same size.
