Weeki Wachee, Florida
Weeki Wachee is home to just four residents according to the city's homepage, making it the only city in the world with more mermaids than people. The deepest naturally formed spring in the U.S. runs through this small town, and Seminole Indians named it "Weeki Wachee," meaning "little spring." The spring is so deep that the bottom has never been located, and every day more than 117 million gallons of fresh water flow into the spring from subterranean caves.
When former U.S. Navy SEAL trainer Newton Perry came across the spring in 1946, he saw a business opportunity and built a theater into the limestone below the surface of the spring. Perry trained women as "mermaids," teaching them to swim, dance and perform beneath the water, and the Weeki Wachee mermaids were born. The mermaids transformed Weeki Wachee into a tourist hotspot in the 1960s, attracting thousands of people to the small town, including celebrities like Elvis Presley. The city incorporated in 1966, making it one of the nation’s smallest cities — and the only one with a mermaid mayor. Mayor and former mermaid Robyn Anderson now oversees both the city and her underwater kingdom of mermaids.
