Location and boundaries
Historically, the former Town of Castleton was platted near present-day 82nd St. and the former Nickel Plate Road, about 12 miles (19 km) northeast of downtown Indianapolis. The "neighborhood area" encompasses a greater geography than the historic town, which is the basis for sociodemographic data collection.[a] Castleton is bounded by 96th St. (north), White River (west), Interstate 69 (east), and 82nd St. and Interstate 465 (south).
Castleton was founded in 1852 by Thomas Gentry. The small town prospered as a service center for nearby farmers and travelers on the Nickel Plate Road. In the proceeding decades, the town saw gradual development, with a church, grade school, grain elevators, and a railroad depot. The first town board meeting occurred in 1906. In 1950, the town recorded a population of 268.
In 1965, county officials rezoned the area for commercial and light industrial land uses in anticipation of the local Interstate Highway System. The construction of Interstates 69 and 465 forced the demolition of some properties in Castleton, including a church, Masonic temple, and school. On January 1, 1970, Castleton became an "included town" under the consolidated city-county government of Indianapolis and Marion County (Unigov). In 1972, Castleton Square opened as the largest enclosed shopping mall in Indiana. Suburban development accelerated upon the mall's opening, with the construction of several single-family subdivisions, apartment complexes, shopping centers, and office parks in the 1980s and 1990s.
On November 18, 1991, the town board voted to dissolve the town of 37 residents. Indianapolis Mayor Stephen Goldsmith authorized the dissolution effective on January 19, 1992. Today, Castleton remains one of the metropolitan area's highest concentrations of commercial office and retail space. According to reporting from the Indianapolis Business Journal, the neighborhood is home to 2,800,000 sq ft (260,000 m2) of retail and more than 900,000 sq ft (84,000 m2) of commercial office.
