Due to the reaction of the metal to the summer heat, the Eiffel Tower experiences thermal expansion, which causes it to increase an average of 15 centimetres (six inches) in height throughout the season. The tower’s height expanded by an astonishing 18 centimetres (seven inches) in 1976 due to heat-induced expansion, which is the most substantial growth ever recorded for the structure.
The Eiffel Tower receives a new coat of paint around once every seven years, in addition to its fascinating growing phenomena. The tower’s colour has changed several times, starting as Venetian red, then moving on to ochre yellow. Chestnut brown, eventually settling on the bronze colour it has today, which was chosen as recently as 1968.
It will take significant time and resources to repaint the tower’s surfaces, which total approximately 250,000 square metres (2.6 million square feet). During this operation, around 60 metric tonnes of varnish, 1,500 paintbrushes, and 1,000 pairs of gloves are utilised. Surprisingly, the painting process takes roughly 18 months to complete, and astonishingly, the Eiffel Tower continues to welcome guests throughout this extensive restoration time.
