No, the Statue of Liberty was not always green. Its iconic green color is the result of a natural chemical process.
When the statue was unveiled in 1886, it was the color of a shiny new penny—a dull brownish-gold. This was its original color because its “skin” is made of copper sheets, about the thickness of two pennies.
The change happened due to patination, a process where copper reacts with elements in the air.
While the green patina is now a cherished part of the statue’s identity, it wasn’t universally loved at first. In the early 1900s, there were serious debates about painting or cleaning the statue to restore its original copper color. Fortunately, engineers recognized that the patina actually protects the underlying copper from further corrosion, acting as a natural shield. For this reason, it was left alone.
So, in summary: The Statue of Liberty started as a brownish-copper color and gradually turned green over a couple of decades due to natural weathering. Its green “skin” is now an essential, protective part of its structure
