Noblesville is a city in and the county seat of Hamilton County, Indiana, United States, located just north of Indianapolis. The population was 51,969 at the 2010 census making it the 14th largest city/town in the state, up from 19th in 2007. The city is part of Delaware, Fall Creek, Noblesville, and Wayne townships.
Noblesville's history dates back to 1818 when the land, which is now Hamilton County, was purchased by the government from Indians native to this area. William Conner, the only settler living in the area at the time, and his wife, a Delaware Indian, established the first trading post in central Indiana in 1802 and lived in the first log cabin in the area. William Conner and Josiah Polk laid out what is now downtown Noblesville in 1823, which was designated as the Hamilton County seat in 1824 and incorporated in 1851. Conner's 1823 home is now one of a village of historic buildings making up Conner Prairie Pioneer Settlement, a living history museum south of Noblesville in Fishers.
Noblesville was named either for James Noble, one of the first two US senators from Indiana, or according to legend, for Lavina Noble of Indianapolis, to whom Josiah Polk was engaged.
The Peru and Indianapolis Railroad was completed through town in 1851, strengthening the town economically and causing the population to increase. In 1875 work was begun on the town's second railroad, the Anderson, Lebanon and St. Louis, later known as the Midland.
The city's first large growth boom came in 1888 with the discovery of Noblesville's first natural gas well near 11th and Pleasant streets. Many Victorian homes, as well as the vast majority of the Downtown Commercial District, were built during this time of prosperity. The city's second large growth was particularly recent increasing its population from 28,590 in 2000 to 51,969 in 2010. This growth echos the increase in population of much of southern Hamilton County as a preferable place for people to live who enjoy a close proximity to the Indianapolis area.
Noblesville was once noted for its flour mills, the mostly widely known of which was the Noblesville Milling Company, producer of Diadem and Kismet flours. In 1925, the manager of the company offered to buy uniforms for the local high school athletic team in exchange for school adopting the nickname “Millers.” The nickname persists to this day.
Other prominent businesses of the past include the Union Sanitary Manufacturing Company, the American Strawboard Company and Firestone Industrial Products.
Among the notable disasters to have struck the town are the Flood of 1913, an interurban wreck on the courthouse square in 1919  and the Goeke fire of 1967. The fire, which began at the Paul Goeke auto dealership just off the square, destroyed two buildings and took the life of one firefighter.
The old Hamilton County Sheriff’s Residence and Jail on the southwest corner of the courthouse square in downtown Noblesville is now the home of the Hamilton County Museum of History, but as a working jail it once housed a teenage Charles Manson and D.C. Stephenson, former Grand Dragon of the Indiana Ku Klux Klan.
The Stephenson trial, which took place in the nearby Hamilton County courthouse in 1925, broke the power of the Klan in Indiana and drew national attention to Noblesville. Stephenson was convicted of second-degree murder in the death of Madge Oberholtzer.
During the early 1920s Noblesville was one of several Indiana towns in which the Ku Klux Klan was active, but the Klan’s influence quickly faded in the wake of Stephenson’s conviction. In 1973 Klansmen staging a march in Noblesville were met by counter-demonstrators carrying anti-Klan placards.
In 1995 a local contractor stumbled across a trunk containing Klan paraphernalia and membership records from the 1920s era. The discovery sparked a debate over how to handle the sensitive issue and again put Noblesville in the national spotlight.
Noblesville also attracted national media attention in 1965 when Noblesville Daily Ledger editor James T. Neal was charged with contempt by Hamilton County Circuit Court judge Ed New. Neal’s fight for the First Amendment went before the Indiana Supreme Court.
The centerpiece of downtown Noblesville is the Courthouse Square, the location of the Hamilton County Courthouse (completed in 1879) and the Hamilton County Sheriff's Residence and Jail (constructed in 1876). Both buildings are fabulous examples of the Second Empire style featuring mansard roofs. There are also several sites and buildings in Noblesville that are listed on the National Register of Historic Places including the Hamilton County Courthouse Square, the Catherine Street Historic District, Conner Street Historic District, William Houston Craig House, Daniel Craycraft House, Holliday Hydroelectric Powerhouse and Dam, Noblesville Commercial Historic District and the Noblesville Milling Company Mill.
Noblesville is located at (40.049935, -86.021462).
According to the 2010 census, the city has a total area of 32.79 square miles (84.9 km2), of which 31.37 square miles (81.2 km2) (or 95.67%) is land and 1.42 square miles (3.7 km2) (or 4.33%) is water.
Noblesville is known as the middle of the Corn Belt. According to the 2000 U.S. Census the mean population of Ohio, Indiana, Michigan, Illinois, and Iowa can be found in Noblesville. Whether Noblesville retains this distinction remains to be seen. Reduced employment and emigration from the Detroit region may shift the population towards Bloomington, IL.
