The Indiana World War Memorial Plaza Historic District strongly defines the character of downtown Indianapolis. The plaza comprises six aligned square city blocks of monumental public architecture and landscape architecture, united into a cohesive whole.
Listed on the National Register of Historic Places, this example of Neo-classic architecture was built in 1927 by W. M. Nissen with funds from his Nissen Wagonworks family fortune, a company dating back to 1787. Nissen lived on the 20th floor of the building.
