Step into the Lincoln Memorial: A dialogue with history.

The Lincoln Memorial is considered an eternal statue and a symbol of Washington, D.C., built to commemorate the 16th President of the United States, Abraham Lincoln. The memorial is located on the west side of the National Mall in Washington, D.C., on the east bank of the Potomac River, and faces the Capitol on the east side. It is a Greek temple-style memorial built with white granite and marble. The designer of the memorial, Henry Bacon, knew the symbolic significance of the memorial to reunite the country that was torn apart by the Civil War, and deliberately selected building materials from as many states as possible. The granite terrace layer comes from Massachusetts, the upper steps and outer decorations of marble come from Colorado, and the pink marble floor of the main hall comes from Tennessee. Limestone from Indiana is used to make interior walls and main hall columns, and the ceiling panels are made of marble from Alabama. The Lincoln statue is carved from marble from Georgia. Bacon was awarded the Gold Medal of the American Institute of Architects for his outstanding work on the memorial, which is the highest honor in his career. For nearly a century, the steps of the Lincoln Memorial have witnessed many historic moments, such as Martin Luther King's famous speech "I Have a Dream". In 2003, the position where Martin Luther King stood at the time was engraved to commemorate the 40th anniversary of the speech. The memorial is full of the style of classical Greek temples, and the entire building covers an area of 58 x 36 meters and is 30 meters high. It is surrounded by a colonnade composed of 36 Doric columns with grooves. The columns are 13 meters high and 2.3 meters in diameter at the bottom, symbolizing the 36 states of the Union when Lincoln died. Above it, the names of the 48 states of the Union when the memorial was completed are engraved. Walking up the stairs into the memorial and looking up, you can see a classic quote engraved on the wall: "In this temple as in the hearts of the people for whom he saved the Union, the memory of Abraham Lincoln is enshrined forever." The Lincoln statue is 5.8 meters high and weighs 175 tons. His gaze is towards the east, across the National Mall towards the Washington Monument, praising the founding father of the United States, George Washington, and they are separated by a long reflecting pool. The left side of the statue is engraved with President Lincoln's Gettysburg Address. The Gettysburg Address was delivered during the American Civil War. It is the most famous speech by former US President Lincoln and the most quoted speech in American history. The Lincoln Memorial has played a major role in many sensational movies, and also appears on the back of the $5 bill, with Lincoln's portrait on the front. The memorial is visited by about 6 million people each year, and is open all day, all year round (except December 25). There are mounted police on duty every day from 9:30 in the morning to 10:00 in the evening.
