Key West. Key West is an island in the Straits of Florida, within the U.S. state of Florida. Together with all or parts of the separate islands of Dredgers Key, Fleming Key, Sunset Key, and the northern part of Stock Island, it constitutes the City of Key West. The island of Key West is about 4 miles long and 1 mile wide, with a total land area of 4.2 square miles. It lies at the southernmost end of U.S. Route 1, the longest north-south road in the United States. Key West is about 95 miles north of Cuba at their closest points. It is also 130 miles southwest of Miami by air, about 165 miles by road, and 106 miles north-northeast of Havana. The city of Key West is the county seat of Monroe County, which includes a majority of the Florida Keys and part of the Everglades. The total land area of the city is 5.6 square miles. The population within the city limits was 26,444 at the 2020 census. The official city motto is One Human Family. Key West is the southernmost city in the contiguous United States and the westernmost island connected by highway in the Florida Keys. Duval Street, its main street, is 1.1 miles in length in its 14-block-long crossing from the Gulf of Mexico to the Straits of Florida and the Atlantic Ocean. Key West is the southern terminus of U.S. Route 1, State Road A1A, the East Coast Greenway and, before 1935, the Florida East Coast Railway. Key West is a port of call for many passenger cruise ships. The Key West International Airport provides airline service. Naval Air Station Key West is an important year-round training site for naval aviation due to the tropical weather, which is also the reason Key West was chosen as the site of President Harry S. Truman's Winter White House. The central business district is located along Duval Street and includes much of the northwestern corner of the island. At various times before the 19th century, people who were related or subject to the Calusa and the Tequesta inhabited Key West. The last Native American residents of Key West were Calusa refugees who were taken to Cuba when Florida was transferred from Spain to Great Britain in 1763. Cayo Hueso is the original Spanish name for the island of Key West. It literally means bone cay, cay referring to a low island or reef. It is said that the island was littered with the remains of prior native inhabitants, who used the isle as a communal graveyard. This island was the westernmost Key with a reliable supply of water. Between 1763, when Great Britain took control of Florida from Spain, and 1821, when the United States took possession of Florida from Spain, there were few or no permanent inhabitants anywhere in the Florida Keys. Cubans and Bahamians regularly visited the Keys, the Cubans primarily to fish, while the Bahamians fished, caught turtles, cut hardwood timber, and salvaged wrecks. Smugglers and privateers also used the Keys for concealment. In 1766 the British governor of East Florida recommended that a post be set up on Key West to improve control of the area, but nothing came of it. During both the British and Spanish periods no nation exercised de facto control. The Bahamians apparently set up camps in the Keys that were occupied for months at a time, and there were rumors of permanent settlements in the Keys by 1806 or 1807, but the locations are not known. Fishermen from New England started visiting the Keys after the end of the War of 1812, and may have briefly settled on Key Vaca in 1818. In 1815, the Spanish governor of Cuba in Havana deeded the island of Key West to Juan Pablo Salas, an officer of the Royal Spanish Navy Artillery posted in Saint Augustine, Florida. After Florida was transferred to the United States in 1821, Salas was so eager to sell the island that he sold it twice-first for a sloop valued at $575 to a General John Geddes, a former governor of South Carolina, and then to a U.S. businessman John W. Simonton, during a meeting in a Havana café on January 19, 1822, for the equivalent of $2,000 in pesos in 1821. Geddes tried in vain to secure his rights to the property before Simonton who, with the aid of some influential friends in Washington, was able to gain clear title to the island. Simonton had wide-ranging business interests in Mobile, Alabama. He bought the island because a friend, John Whitehead, had drawn his attention to the opportunities presented by the island's strategic location. John Whitehead had been stranded in Key West after a shipwreck in 1819 and he had been impressed by the potential offered by the deep harbor of the island. The island was indeed considered the Gibraltar of the West because of its strategic location on the 90-mile-wide deep shipping lane, the Straits of Florida, between the Atlantic Ocean and the Gulf of Mexico.
