English: Built in 1926-1933, this Classical Revival-style building was designed by Walker and Weeks to serve as a memorial to veterans and the war dead of World War I, as a bid by Indianapolis to attract the headquarters of the American Legion to the city. The structure was based on the Mausoleum of Halicarnassus, one of the Seven Wonders of the Ancient World, and anchors the Indiana World War Memorial Plaza, a large open-air public park in the middle of Downtown Indianapolis that was built according to City Beautiful principles, with the master plan having been completed by Walker and Weeks in 1923. The 210-foot (64 meter) tall building is clad in Indiana limestone with a two-tier massing, a rusticated stone base, a terrace at the top of the first tier with urns at the corners, large staircases up to the terraces and a stone balustrade around the exterior of the terrace, a stone base at the bottom of the second tier, bronze doors, decorative torchiere-style light fixtures, tall ionic colonnades on each face of the middle of the second tier of the structure with an architrave featuring reliefs and a cornice with dentils, statutes, above the colonnades, and a pyramidal hipped roof. The building is a contributing structure in the Indiana War Memorial Plaza Historic District, listed on the National Register of Historic Places in 1989, and designated a National Historic Landmark District in 1994. The building today serves as a memorial to Indiana’s World War I dead, and houses a museum and auditorium.
