The Lincoln Memorial, on the extended axis of the National Mall in Washington, D.C., is a United States Presidential Memorial built to honor President Abraham Lincoln. The building is in the form of a Greek Doric temple, and contains a large seated sculpture of Abraham Lincoln and inscriptions of two well-known speeches by Lincoln. The memorial has been the site of many famous speeches, including Martin Luther King's "I Have a Dream" speech, delivered on August 28, 1963, during the rally at the end of the March on Washington for Jobs and Freedom. Like the other monuments on the National Mall, including the nearby Vietnam Veterans Memorial, Korean War Veterans Memorial, and National World War II Memorial, the Lincoln Memorial is administered by the National Park Service under its National Mall and Memorial Parks group. The National Memorial was listed on the National Register of Historic Places on October 15, 1966. It is open to the public from 8 a.m. until midnight all year, except December 25.
