The Lincoln Memorial is an American national monument built to honor the 16th President of the United States, Abraham Lincoln. Since opening to the public in 1922, the memorial has become one of the most iconic and beloved structures in America.
The exterior of the Memorial echoes a classic Greek temple and features Yule marble from Colorado. The structure measures 189.7 by 118.5 feet and is 99 feet tall. It is surrounded by a peristyle of 36 fluted Doric columns, one for each of the 36 states in the Union at the time of Lincoln's death, and two columns in-antis at the entrance behind the colonnade. The columns stand 44 feet tall with a base diameter of 7.5 feet.
