"In this temple, as in the hearts of the people for whom he saved the Union, the memory of Abraham Lincoln is enshrined forever."Beneath these words, the 16th President of the United States—the Great Emancipator and preserver of the nation during the Civil War—sits immortalized in marble. Since its dedication on Memorial Day, 1922, the Lincoln Memorial has become the site of some of the nation’s most important social demonstrations, perhaps most notably Dr. Martin Luther King, Jr.’s “I Have a Dream” speech.Lincoln is surrounded by 36 Doric columns, one for each state at the time of his death. By the time construction was finished, 12 more states had joined the Union, so the names of all 48 states are carved around the top of the 99 foot tall structure. A plaque for Alaska and Hawaii was added later. The Southern and Northern interior walls of the memorial are inscribed with the full text of Lincoln’s Gettysburg Address and 2nd Inaugural Address, respectively. Construction was completed in May, 1922 and the Lincoln Memorial was dedicated on Memorial Day, May 30, 1922. https://www.nps.gov/linc/index.htm

Built to honor George Washington, the United States' first president, the 555-foot marble obelisk towers over Washington, D.C.George Washington's military and political leadership were indispensable to the founding of the United States. As commander of the Continental Army, he rallied Americans from thirteen divergent states and outlasted Britain's superior military force. As the first president, Washington's superb leadership set the standard for each president that has succeeded him. The Washington Monument towers above the city that bears his name, serving as an awe-inspiring reminder of George Washington's greatness. The monument, like the man, stands in no one's shadow.The Washington Monument, designed by Robert Mills and eventually completed by Thomas Casey and the U.S. Army Corps of Engineers, honors and memorializes George Washington at the center of the nation's capital. The structure was completed in two phases of construction, one private (1848-1854) and one public (1876-1884). Built in the shape of an Egyptian obelisk, evoking the timelessness of ancient civilizations, the Washington Monument embodies the awe, respect, and gratitude the nation felt for its most essential Founding Father. When completed, the Washington Monument was the tallest building in the world at 555 feet, 5-1/8 inches. https://www.nps.gov/wamo/index.htm
