Torrington is the largest city in Litchfield County, Connecticut and the northwestern Connecticut region. It is also the core city of the largest micropolitan area in the United States. The population was 36,248 at the 2000 census.

Torrington is a former mill town, as are most other towns along the Naugatuck River Valley. It is currently competing with the neighboring city of Winsted to recreate a pleasant Main Street environment. Downtown Torrington is home to the Nutmeg Conservatory for the Arts, which trains ballet dancers and whose Company performs in the Warner Theatre, a 1,700 seat auditorium restored in 2002 to its original 1931 glory. The theater, while originally built as a cinema by the Warner Brothers film studio, has been reborn as a performing arts venue and arts instruction organization, and will serve as a cornerstone of the city's downtown revitalization project. Downtown Torrington also hosts the largest Lodge of Elks in New England.

Torrington, originally Wolcottville, was first settled in 1735 by Ebenezer Lyman Jr. of Durham, Connecticut. Its early settlers resided on the hills west of the Naugatuck River where the first school, church, store, and tavern were constructed. Later, the eastern hill known as Torringford was settled as it provided the best farmland for agricultural work. Torrington was given permission to organize a government and incorporate as a town in October of 1740.

The fast moving waters of the Naugatuck River were utilized as waterpower for early 19th century industries. Industrial growth skyrocketed in 1813 when Frederick Wolcott constructed a woolen mill. The mill attracted a large workforce and created a demand for goods, services, and housing.

Israel Coe and Erastus Hodges began the construction of two brass mills on the Naugatuck River in 1834. This event sparked the beginning of the brass industry in Torrington, which would later spread throughout the entire Naugatuck Valley. In 1849, the Naugatuck Valley railroad was completed which connected Torrington with other population centers, ending its isolation and stimulating further industrial growth. Soon, Torrington was producing a variety of metal products including needles, brass, hardware, bicycles, and tacks. Torrington's growing industrial plants attracted English, Irish, and German immigrants throughout the 19th and early 20th century. Between 1880 and 1920, Torrington's population exploded from 3,000 to 22,000 as immigration from southern and eastern Europe increased. During this period, immigrants included the Poles, Czechs, Slovaks, Italians and Lebanese. Torrington was chartered as a city in 1923.

In 1955, a massive flood destroyed much of the downtown area and property in the region when Hurricane Connie and Hurricane Diane caused local rivers to overflow.

Torrington is the birthplace of abolitionist John Brown.

According to the United States Census Bureau, the city has a total area of 40.4 square miles (104.6 km²). Approximately 39.8 square miles (103.1 km²) of it is land and 1.5 km² (0.6 sq mi or 1.41%) of it is water.

The eastern and western sides of the city, at its borders, are at the tops of peaks, while the downtown and central sections of the city are in the Naugatuck River Valley. This provides some interesting views from the higher locations, with the city lights as a backdrop below. Due to the lack of suitable highways and bypass routes in an East/West direction, crossing the city requires driving down into the valley and back up the other side.

As of the census of 2000, there were 35,202 people, 14,743 households, and 9,125 families residing in the city. The population density was 884.7 people per square mile (341.6/km²). There were 16,147 housing units at an average density of 405.8/sq mi (156.7/km²).

The historic restoration and renovation to downtown Coe Memorial Park were completed in the beginning of 2004. The Coe Memorial Park Subcommittee and the City of Torrington, worked closely with Ferrero Hixon Associates, to restore the Park to a Victorian walking park, much as it was when it was first gifted to the Town in 1906. These renovations included new sidewalks and paths, and the relocation of memorials and monuments. In 2005, award winning horticulturist, Gwenythe b. Harvey, owner of the firm The Garden Goddess, LLC, was hired to redefine, design and upgrade existing garden areas. Coe Memorial Park's Botanical Gardens has since become a well-known tourist destination.

The east end of the city known as Torringford, along U.S. Route 202, has been undergoing a period of non-stop, rapid expansion since 1996, when a shopping complex was built on the corner of Rte 202 and 183 with a Wal-Mart, Price Chopper, Sears Hardware (which has since closed due to competition from nearby Home Depot in neighboring New Hartford) and McDonald's. A Circuit City had been built where Sears Hardware was previously located, but has since closed. Led by the development of multiple shopping centers at that time, the once empty farm land has become home to many chains that are new to the city. Among the current projects are the construction of a new Walgreens drug store, the relocation of a local bank branch and the opening of a new car wash. Expected to begin soon is the construction of a new Stop & Shop supermarket. Construction has already completed on a plaza anchored by a Target department store. Target opened in October 2007. Sleepy's, Panera Bread, Bed Bath & Beyond, Game Stop and Famous Footwear have also been built in the Target development.

A professional baseball team once located in the city was known as the Torrington Braves, and were a member of the Colonial League. After just one season, 1950, they dispanded.

The Torrington Twisters were a member of the New England Collegiate Baseball League (NECBL) from 1997-2008. Torrington during this period had twice played host to the league All-Star Game (1998, 2008) and generally placed high in their division each season. The organization moved to Massachusetts in 2008 to become the New Bedford Bay Sox, after being unable to negotiate a fair contract with the City and the Torrington Park % Recreation Commission.

Running

The Torrington Road Race is a five-mile (8 km) run, which coincides with Donor's Week in August. Starting at Coe Memorial Park, the course extends to the farther reaches of the valley, including Riverside Avenue, Migeon Avenue, Prospect Street and others. The race, which started in 1972, primarily includes runners from around Connecticut. Not the magnitude of the Litchfield Hills Road Race in neighboring Litchfield, the race peaked with 267 finishers in 2003. It has grown to have also attracted some runners each year from Massachusetts, New York, New Jersey and Pennsylvania.
