The Peace Monument commemorates naval deaths during what conflict?
Dedicated in 1878, 13 years after the American Civil War’s completion, the National Mall’s Peace Monument is specifically dedicated to naval deaths suffered during America’s darkest hour. The 44-foot-tall, white marble Peace Monument is located just adjacent to the U.S. Capitol, though it was initially intended to be built in Annapolis, Maryland, before D.C. became its permanent home.
