The Prairie Avenue District is a historic district in the Near South Side community area of Chicago, Illinois. It includes the 1800 and 1900 blocks of South Prairie Avenue and the 1800 block of South Indiana, and 211-217 East Cullerton. It was the site of the Battle of Fort Dearborn and became the city's most fashionable residential district after the Great Chicago Fire. It was designated a Chicago Landmark on December 27, 1979. The district was added to the National Register of Historic Places on November 15, 1972. The John J. Glessner House, designed and built by Henry Hobson Richardson in 1885–1886 at 1800 S. Prairie Avenue, has been restored as a historic house museum, and is open for public tours. In 2006, the Prairie District Neighborhood Alliance, a non-profit organization was formed to provide representation for thousands of South Loop residents, including the Prairie Avenue District, Central Station, Museum Park, Motor Row, and the South Michigan Avenue Corridor, as well as other areas of the Near South Side.
