Rising above the Reflecting Pool like a Greek temple, this elegant landmark was finished in 1922 and was built as a tribute to Abraham Lincoln, the 16th president of the United States. Inside, a large central chamber contains an imposing statue of the late president himself, while murals are intended to depict principles such as liberty and unity.

The monument stands proud at the western end of Washington DC's National Mall.
