Savannah is the largest city and county seat of Chatham County, in the U.S. state of Georgia. Established in 1733, the city of Savannah was the colonial capital of the Province of Georgia and later the first state capital of Georgia. Today Savannah is an industrial center and an important Atlantic seaport. Each year Savannah attracts millions of visitors, who enjoy the city's architecture and historic buildings: the birthplace of Juliette Gordon Low (founder of the Girl Scouts of the United States of America), the Telfair Academy of Arts and Sciences, the First African Baptist Church (one of the oldest African American Baptist congregations in the United States), Temple Mickve Israel, and the Central of Georgia Railway roundhouse complex (the oldest standing antebellum rail facility in America). Savannah's downtown area, which includes the Savannah Historic District, the Savannah Victorian Historic District and 22 parklike squares, is one of the largest National Historic Landmark Districts in the United States.
