One of the symbols of America’s independence and freedom, Mount Rushmore is an homage to the four great presidents of the United States. Also known as the President’s Mountain, Mount Rushmore in South Dakota immortalizes the faces of the four American presidents that changed the faith of the country. From left to right, these are George Washington, Thomas Jefferson, Theodore Roosevelt, and Abraham Lincoln. Work on sculpting the 60-foot tall figures began in 1927 and was finalized in 1941. At the time, the project cost nearly $1 million to complete. It was 10 times the initial estimated price. Nowadays, the sum would translate into $11 billion in present day dollars, making the statues at Mount Rushmore the most expensive in the world, reaching number one on our list.
