Famous American buildings made out of limestone
Limestone has been utilised throughout the ages and is a popular material within building and construction. We take a look at famous American buildings made out of limestone which still remain today and are iconic within America.
The Pentagon, United States
At 6,500,000 square feet, the Pentagon in Arlington County, Virginia is the world’s largest office building and serves as the headquarters for the United States Department of Defense.
Designed by American architect George Bergstrom and constructed by contractor John McShain, reinforced concrete was implemented alongside Indiana limestone for the building’s exterior as a result of the lack of steel from the Second World War.
Rebuilt after September 11 2001, the building now houses over 23,000 employees and is one of the most famous buildings within America.

Constructed to honour Abraham Lincoln, 16th President of the United States, the Lincoln Memorial was built between 1914 and 1922. Designed by architect Henry Bacon and incorporating classical features, the build also has a statue of Lincoln within the interior, constructed by Daniel Chester French.
Interior walls and columns are made from Indiana limestone, beside marble and granite which have been utilised to represent different areas within the United States.
The area is still a tourist attraction and has become listed on the National Register of Historic Places since 1966.
