The Florida Keys are a coral island archipelago near the southeastern tip of the US state of Florida, starting about 15 miles (24 km) south of Miami and extending out in a southwest direction and then west toward the Gulf of Mexico. The islands lie along the Florida straits.

I hope that you enjoy reading my facts about the Florida Keys and find them interesting.

8. Because the Florida Keys archipelago is made up of many islands, the keys are often split up into groups. The group of islands farthest north are known as the Upper Keys. Below them are the groups known as the Middle Keys and the Lower Keys (Key West is located in the Lower Keys). A fourth group is known as the Outer Keys and is made up of islands that can only be accessed by boat.

9. The term “key” is a corruption of the Spanish word, “Cayo”, which means small island.

10. For a long time, Key West was the largest and busiest town in the whole of Florida, because it was close to the Bahamas and Cuba and provided a trade route up to New Orleans.

11. Key West and the Florida Keys were also associated with the wrecking industry for many years, with the workload peaking in the middle of the 19th Century, as more and more ships traveled the trade routes between the east coast of the USA, the Gulf of Mexico, and the Carbbean Sea. Heavy shipping, strong currents, and dangerous reefs meant that shipwrecks were occurring at a rate of once per week at one time.

12. Henry Flagler's Overseas Railway, which connected Key West to mainland Florida, was completed in the early 1910s, despite work being disrupted by hurricanes in 1906, 1909, and 1910.

13. In 1935 the Florida Keys were hit by one of the worst hurricanes ever to strike the USA. Winds with speeds of 200 miles per hour (320 km per hour) battered the islands and a storm surge of over 17.5 feet (5.3 m) flooded them. 500 people died in the hurricane and the Overseas Railway was severely damaged. (The hurricane occurred on Labor Day and is often referred to as the Labor Day Hurricane.)

14. The Overseas Highway was built to replace the Overseas Railway, after it was damaged by the 1935 hurricane, and the railroad bridges were converted to automobile roadways.

The city of Key West is the southernmost city in the continental United States and also the county seat of Monroe County.  It is 129 miles (208 km) southwest of Miami, Florida and 106 miles (171 km) north-northeast of Havana, Cuba.

15. The climate of the Florida Keys is classified as tropical. The weather is hot and humid from June to October and relatively drier and cooler from November to May. The Keys are the only frost-free place in Florida.

16. Key West traditionally has strong ties with Cuba and after the revolution, many Cubans settled there. The Keys still experience escaping Cubans arriving on rafts from time to time.

Historically, The Keys, and particularly Key West have strong connections with nearby Cuba, originally through trade links.  After the revolution in Cuba, many anti-Communist Cubans came to settle in the Key West area.

20. Since 1981 more than 23 artificial reefs have been created in the waters off the Keys, mainly through the sinking of ships, and these provide a home to many corals, tropical fish and other marine life.
