Jacksonville, Florida's most populous city proper and the tenth-largest U.S. city, sits on the Atlantic coast of northeastern Florida with a 2020 population of 949,611 and a metropolitan area of over 1.76 million residents. Located on the St. Johns River about 12 miles south of the Georgia border, the city covers 900 square miles - the largest total area of any contiguous U.S. city - after consolidating with Duval County in 1968. Originally inhabited by the Timucua people and later Spanish missions including San Juan del Puerto (1513-1763), the settlement was named in 1822 for Andrew Jackson, first military governor of Florida Territory and seventh U.S. president, following Spain's cession of Florida under the 1821 Adams-Onís Treaty. Since the late 19th century, harbor improvements have established Jacksonville as a major deep-water port hosting Naval Station Mayport, Naval Air Station Jacksonville, and JAXPORT, Florida's largest seaport, forming the third-largest military presence in the United States. The local economy centers on banking, insurance, healthcare, logistics, and golf tourism, with the PGA Tour headquarters located in nearby Ponte Vedra Beach. Saint Augustine, located 40 miles south of Jacksonville on Florida's Atlantic coast, is the oldest continuously inhabited European settlement in the contiguous United States, founded on September 8, 1565, by Spanish admiral Pedro Menéndez de Avilés. Named after the feast day of Saint Augustine when settlers first sighted land on August 28, the city served as the capital of Spanish Florida for over 200 years before becoming the territorial capital in 1821 following Spain's cession of Florida to the United States in 1819. Part of Florida's First Coast region and the Jacksonville metropolitan area, Saint Augustine had a population of 14,329 at the 2020 census. Since the late 19th century, the city has been a major tourist destination, with attractions including the 17th-century Castillo de San Marcos fortress and the historic downtown St. George Street featuring over 30 historic houses and attractions. The city is known for its distinctive historical character and role as a symbol of early European settlement in North America. Fernandina Beach is the county seat of Nassau County in northeastern Florida and the northernmost city on Florida's Atlantic coast, situated on Amelia Island as part of the Jacksonville Metropolitan Statistical Area, with a 2020 population of 13,052. Known as the "Isle of 8 Flags," Amelia Island has flown the flags of France, Spain, Great Britain, the Republic of East Florida, the Republic of the Floridas, Mexico, the Confederate States of America, and the United States. Originally inhabited by the Timucua people who settled around 1000 CE calling it Napoyca, the area was claimed by the French, English, and Spanish during the 16th through 18th centuries before Spain formally established the town. On January 1, 1811, Spanish Governor Enrique White named Fernandina in honor of King Ferdinand VII, making it on May 10, 1811, the last town platted under the Laws of the Indies in the Western Hemisphere. The city's strategic location led to its capture and recapture by various forces, including American insurgents in 1812 during the Patriot War and Spanish forces who erected Fort San Carlos in 1816.
