The opposite of DC's white, gleaming marble is this black, low-lying 'V,' an expression of the psychic scar wrought by the Vietnam War. The monument follows a descent deeper into the earth, with the names of the 58,272 dead soldiers – listed in the order in which they died – chiseled into the dark wall. It's a subtle, but profound monument – and all the more surprising as it was designed by 21-year-old undergraduate student Maya Lin in 1981.
