Bridgeport is the most populous city in the U.S. state of Connecticut. Located in and the former county seat of Fairfield County, the city had an estimated population of 137,912 in 2006 and is the core of the Greater Bridgeport area. The city is part of the New York combined statistical area. Bridgeport is also the center of the 41st largest urban area in the United States, just behind Austin, Texas (40th). The city is marked by its attachment to its famous resident, the circus-promoter and once mayor P.T. Barnum. Barnum built three houses in the city, and housed his circus in town during winters. Other than Black Rock and parts of Brooklawn which were originally part of the Town of Fairfield, Bridgeport was originally a part of the Town of Stratford. The first settlement was made in 1659. It was called Pequonnock until 1695, when its name was changed to Stratfield, because of its location between the already existing towns of Stratford and Fairfield. During the American Revolution it was a center of privateering. In 1800, the borough of Bridgeport was chartered, and in 1821 the township was incorporated. The city was not chartered until 1836. The city was home to the Frisbie Pie Company, and therefore it has been argued that Bridgeport is the birthplace of the frisbee. The city is also home to the first Subway Restaurant. The first Restaurant opened in the North End section of the city in 1965. The restaurant is located at 5 corners located on North Main Street, Jewett Avenue, Tesiny Avenue and Beechmont Avenue. The company is still headquartered in the area, in nearby Milford.
