Surprising Facts About Key West You Didn’t Know

One of the most entertaining Key West fun facts is the city’s playful declaration of independence in 1982. Frustrated by a U.S. Border Patrol checkpoint on U.S. Route 1, which caused traffic jams that stretched for 17 miles, Key West’s leaders decided to take matters into their own hands. On April 23, 1982, they humorously seceded from the United States, declaring themselves the “Conch Republic.”

The checkpoint, designed to check vehicles for illegal immigrants and drugs, ended up hurting tourism — the lifeblood of Key West’s economy. The secession was meant as a symbolic protest, but it instantly captured attention and became part of the island’s identity. Locals embraced the name “Conchs,” a term that honors the conch shell, which has long been a symbol of island life.

Today, the spirit of the Conch Republic lives on in the annual Conch Republic Independence Celebration. Every April, the city bursts with life through mock naval battles, parades, and quirky events that celebrate its tongue-in-cheek rebellion. The festivities include live music, food vendors and community gatherings, drawing visitors eager to experience Key West’s unique humor and creativity.

While Key West is now a world-renowned destination, its beginnings were much more humble. Officially incorporated in 1828, the island quickly became a hub for maritime trade and wreck salvaging, also known as “wrecking.” The strategic location of Key West in the Gulf of Mexico made it a natural stopping point for ships, but its dangerous surrounding reefs often led to shipwrecks. Salvagers would recover valuable cargo from these accidents, creating wealth and growth for the small community.

At the time of incorporation, the 1830 U.S. Census listed Key West’s population at just 517 residents. Despite its modest size, the city flourished over the following decades, earning a reputation as one of the wealthiest communities in Florida thanks to its thriving maritime industry. Today, traces of this history can be found throughout the island, from its charming architecture to its museums dedicated to preserving the legacy of its early settlers.

Visitors walking through Old Town Key West can see well-preserved 19th-century homes, some of which belonged to early wreckers and prominent families who helped shape the island’s future. This fascinating blend of history and culture makes Key West one of the most intriguing places to explore in Florida.

While Harry S. Truman is most often associated with Key West, the honor of being the first U.S. president to visit the island belongs to Ulysses S. Grant. In 1880, 11 years after leaving office, Grant arrived in Key West alongside Civil War General Phil H. Sheridan. The two men were traveling to Havana, Cuba, aboard a steamship, but they made a stop to explore Key West for the day.

At that time, Key West was one of the most prosperous cities in Florida. Its booming industries, including shipwreck salvaging and salt production, made it a hub of economic activity. Grant’s visit — though short — highlighted Key West’s growing prominence. Today, visitors can dive into Key West fun facts like this by exploring historic sites, museums, and walking tours that showcase the island’s storied past.

Before it was known as Key West, Spanish settlers referred to the island as Cayo Hueso, which translates to “Bone Island.” This name wasn’t chosen by accident. When the Spaniards first arrived, they found the island littered with human bones, sparking curiosity and intrigue. The bones are believed to have belonged to Native Americans, possibly left behind from battles or as part of burial rituals. The sight was so striking that the name stuck, even as the island evolved into the tropical paradise it is today.

In the 19th century, Key West played a vital role in salt production, earning its place as a leading supplier of salt in the United States. The island’s flat terrain and intense heat made it ideal for salt harvesting, as seawater was collected in shallow ponds and left to evaporate naturally.
