Washington, D.C.’s most highly trafficked Greek Doric temple is getting a multi-million dollar makeover—or at least the cavernous space beneath it is. 

As revealed this week by the U.S. National Park Service, the Lincoln Memorial, completed in 1922 as the final project of Beaux-Arts heavyweight and Charles McKim mentee Henry Bacon, will be the future home of a 15,000 square foot “immersive museum” that will use multimedia presentations to delve into the rich history of the site with a focus on its construction and its enduring role as an “international icon dedicated to the achievements of Abraham Lincoln and individuals such as Marian Anderson and Dr. Martin Luther King, Jr., who have shaped the history of the memorial," said the NPS in its President's Day–timed announcement.
