The Indiana World War Memorial Plaza is an urban feature located in Indianapolis, Indiana, originally built to honor the veterans of World War I. The five-city-block plaza was conceived in 1919 as a location for the national headquarters of the American Legion and a memorial to the state's and nation's veterans. At the north end of the plaza is the American Legion Mall, which is the site of the administration buildings of the Legion, as well as a memorial cenotaph. South of that is the Veterans Memorial Plaza with its obelisk.
