Yes. On the hottest summer days, the Eiffel Tower stands roughly 12 to 15 centimeters taller than it does in winter, because the heat makes its iron expand.
Almost every solid expands a little when it warms. Heat gives the atoms inside a material more energy, they jostle harder, and they push slightly farther apart. One iron beam barely changes — but the Eiffel Tower is a stack of iron beams more than 300 meters tall, and all those tiny expansions add up into centimeters you can actually measure.
The sun doesn't heat the tower evenly. The face turned toward the sun warms up and expands more than the shaded face, so over the course of a day the top of the tower tips a small amount away from the sun. As evening cools everything down, it settles back. Engineers who work on bridges and rail lines plan around this same effect every day — the Tower just makes it famous.
