Explanation:

[STC002573] Celebrate Lincoln, Washington, Jefferson, and much more on the National Mall—which is generally defined by the Lincoln Memorial on the west end, the Capitol building on the east end, and everything in between. You can literally spend all day at the Mall, visiting the Smithsonian Museums, memorials to a number of America’s greatest presidents, and of course exploring the U.S. Capitol and the White House. In addition, you have the opportunity to pay your respects at the memorials for the Vietnam War, the Korean War, and World War II. The National Museum of African American History and Culture is the most recent addition to the expansive stretch of buildings and monuments that make up the Mall, which has been considered a “work in progress” for the past 200 years.
