City Place I and Goodwin Square
Downtown Hartford is home to such corporations as * The Hartford, Travelers Insurance, The Hartford Steam Boiler, Phoenix Insurance, Prudential Retirement and United Technologies Corporation, most of which are housed in office towers constructed over the last 20–30 years. Downtown also serves as the hub for bus routes of Connecticut Transit Hartford. Union Station is located in the western part of downtown.
Downtown is also home to the Hartford City Hall, the Hartford Public Library, which is undergoing a major expansion and renovation, the Old State House, which is one of the oldest state houses in the nation, the Wadsworth Atheneum which is the oldest public art museum in the country, The Travelers Tower, historic Hotel Bond, Bushnell Park, and the Connecticut State Capitol and Legislative Office Complex.
The south downtown area south of Bushnell Park is the site of several imposing buildings built in the early decades of the 20th century as the headquarters for large insurance companies. The Scottish Union and National Insurance Company building, in the Georgian Revival style, was built in 1913. The Renaissance Revival-style Connecticut General Life Insurance Company building, built in 1926, was inspired by the Medici-Riccardi Palace in Florence, Italy.
Along Main Street, Capital Community College and the Hartford Public Schools offices are located in the 11-story building that until 1993 housed the G. Fox and Company department store. The newly renovated University of Connecticut School of Business is located at Constitution Plaza. At the eastern edge of downtown at Adriaens Landing the Connecticut Convention Center opened in June 2005 near the new Marriott Hartford Hotel. Another recent major addition to downtown and the city skyline is Hartford 21, a 36-story apartment tower.
