The Statue of Liberty, one of the most iconic landmarks in the world, has undergone a significant transformation since its inception. Designed by French sculptor Frédéric Auguste Bartholdi and built by Gustave Eiffel, the statue was a gift from the people of France to the people of the United States, dedicated on October 28, 1886. However, the statue's original colour was not the green patina we see today, but rather a shiny copper exterior. The copper sheets that covered the statue's internal framework were made from over 300 individual pieces, weighing a total of 62,000 pounds. When the statue was first built, the copper had a reddish-brown colour, which gradually changed over time due to natural weathering processes.
Original Construction and Colour
The statue’s original copper colour was a result of the natural properties of the metal. Copper, when exposed to air and water, undergoes a process called oxidation, which leads to the formation of a layer of copper oxide on its surface. This layer is responsible for the reddish-brown colour of the statue when it was first constructed. The copper sheets used for the statue’s exterior were 3⁄32 of an inch thick and were attached to the internal framework using over 300,000 rivets. The statue’s original colour was not only aesthetically pleasing but also served as a symbol of the friendship between France and the United States.
Weathering and Patination
Over time, the copper exterior of the Statue of Liberty began to undergo a natural process of weathering, which led to the formation of a green patina. This patina is a result of the copper reacting with air, water, and other environmental factors, leading to the formation of copper carbonate and other compounds. The patination process started as early as 1900, just 14 years after the statue’s construction, and has continued to this day. The green patina not only provides a protective layer for the copper but also gives the statue its distinctive appearance. In fact, the patina is so iconic that it has become an integral part of the statue’s identity, with many people unaware of its original copper colour.

Conservation and Restoration
The Statue of Liberty has undergone several restoration efforts over the years to preserve its structural integrity and iconic appearance. In the 1980s, a major restoration project was undertaken to repair the statue’s internal framework, replace the original torch, and preserve the patina. The project involved a team of experts from various fields, including materials science, engineering, and conservation. The restoration efforts not only ensured the statue’s stability but also helped to maintain its unique appearance, including the green patina that has become synonymous with the Statue of Liberty.
Technical Specifications
The Statue of Liberty’s internal framework is made of wrought iron and is designed to be flexible, allowing it to withstand strong winds and other environmental stresses. The framework is supported by a central pylon and four external columns, which provide additional stability. The copper sheets that cover the framework are attached using rivets, and the entire structure is anchored to the pedestal using a system of rods and cables. The statue’s technical specifications are a testament to the ingenuity and skill of its designers and builders, who were able to create a massive and complex structure that has withstood the test of time.
In conclusion, the Statue of Liberty's original colour was a shiny copper exterior, which has undergone a significant transformation over time due to natural weathering processes. The resulting green patina has become an integral part of the statue's identity, providing a unique layer of protection and aesthetic appeal. As we continue to marvel at this iconic landmark, it's essential to appreciate the technical and historical context that has shaped its appearance over the years.
