  • What color was the Eiffel Tower originally painted?

    Q: What color was the Eiffel Tower originally painted?

    A: The 'original' color of the Eiffel Tower can be traced back to two different points: it was painted a brighter red shade called 'Venetian red' when its parts were first being fabricated in 1887-88 (prior to assembly), but it was painted a more subdued reddish-brown hue when it was constructed in 1889. Since its initial construction, this iconic landmark has been repainted an average of once every seven years, or a total 18 times as of 2014. Its color has changed several times, starting off in the red color family, then moving to ochre yellow and finally settling in the specially formulated Eiffel Tower Brown that it has been painted since 1968.
