Commonly known as Mount Rushmore National Memorial is one of the most iconic sites in the United States.
Its singularity lies in that it is a monumental sculptural ensemble of 18 meters high and 5.17 km ² of extension.
It represents the birth, growth, conservation and development of the American nation.
Its construction lasted 14 years and the end result was the reflection on a granite mountain of the faces of
American Presidents George Washington, Thomas Jefferson, Theodore Roosevelt and Abraham Lincoln.
Another curious data of the work is that his sculptors were father and son, Gutzon Borglum and Lincoln Borglum.
