We're used to seeing modern landmarks in their completed glory, but we gain a new appreciation for those familiar monuments when we see them in progress, and remember all the labor that went into bringing them to life.

Statue of Liberty, Liberty Island, New York (Frédéric Bartholdi, 1876-1886)

The torch-bearing arm was displayed at the Centennial Exposition in 1876 and in New York's Madison Square Park from 1876 to 1882.

The head was exhibited at the 1878 Paris World's Fair.

The pedestal's cornerstone was laid in 1884 on Liberty Island, and on June 17, 1885 the Statue of Liberty, a gift to the United States from the people of France, reached the New York port safely. It was dedicated one year later, on October 28, 1886.
