The Statue of Liberty underwent a major renovation for its 1986 centennial, with the most obvious change being the replacement of the torch.
The old flame (left), shown in 1984, featured amber-colored windows and was lighted from within. The openings of the old torch, now in an adjoining museum, allowed rain in and led to corrosion of the arm's support structure, Park Service spokesperson Mindi Rambo said.
The new torch (right), pictured under construction in 1984, has a flame with an unbroken copper skin covered in 24-karat gold leaf and entirely lighted from the outside.
