The Mobile metropolitan area, with an estimated 412,000 people, is the third-most populous metropolitan area in the state. Alabama's only saltwater port, Mobile is located on the Mobile River at the head of Mobile Bay on the north-central Gulf Coast. The Port of Mobile has always played a key role in the economic health of the city, beginning with the settlement as an important trading center between the French colonists and Native Americans, and now to its current role as the 12th-largest port in the United States. During the American Civil War, the city surrendered to Federal forces on April 12, 1865, after Union victories at two forts protecting the city. Considered one of the Gulf Coast's cultural centers, Mobile has several art museums, a symphony orchestra, professional opera, professional ballet company, and a large concentration of historic architecture. Mobile is known for having Mardi Gras, the oldest organized Carnival celebration in the United States. Alabama's French Creole population celebrated this festival from the first decade of the 18th century. Beginning in 1830, Mobile was home to the first organized Carnival mystic society to celebrate with a parade in the United States.
