Washington Street-Monument Circle Historic District, Historic district in Indianapolis, US.

The Washington Street–Monument Circle Historic District covers the first two blocks of East and West Washington and Market streets, Monument Circle, and the first blocks of North and South Meridian Street in downtown Indianapolis. It holds 40 contributing buildings and 2 contributing structures built between about 1852 and 1946, with Italianate, Greek Revival and Art Deco examples. Nineteen of the buildings are individually listed on the National Register.

The district grew with buildings erected between 1852 and 1946, showing different architectural styles of those decades. It was added to the National Register of Historic Places in 1997, marking its importance to Indianapolis's urban development.

The district contains performance venues and a cathedral that together form the cultural heart of downtown Indianapolis. These buildings show how the city has gathered for entertainment and religious gatherings over generations.

The district spreads across the first two blocks of East and West Washington and Market streets, plus Monument Circle and the first blocks of North and South Meridian Street. Start at the circle and walk outward along Washington Street to see the densest cluster of buildings. The terrain is flat and the blocks are short, so a loop of the core takes little time.

On March 19, 1955, the Crispus Attucks High School basketball team became the first all-black school to win an IHSAA state title, but its parade bus did not stop at Monument Circle as earlier white champions' parades had. The route continued to Northwestern Park, and the circle was skipped again after the 1956 title. In 2015, nine team members, including Oscar Robertson, were grand marshals of the IPL 500 Festival Parade and rode through the circle.
