After Lincoln was killed in 1865, people started thinking about his memorial. Work on the building started in 1914.
A spot for it was picked on the National Mall in Washington, D.C. The Mall is a park with monuments and buildings that honor American heroes. For example, the Martin Luther King Jr. Memorial is there.
The plan for Lincoln’s memorial called for materials from all over the country. Special kinds of stone were brought from Massachusetts, Indiana, Alabama, Georgia, and other states.
The builders used materials from the North and the South as a symbol of the unity of the U.S.
Words from Lincoln’s famous speeches were written on the walls.
