The Most Impossible Rise of a City Ever: Palm Beach, Florida

In 1878, a Spanish ship carrying 20,000 coconuts ran aground off a nameless barrier island in southeast Florida. The crew was drunk. The settlers planted the cargo. Within a generation, Standard Oil co-founder Henry Flagler would build the largest wooden hotel in the world on that same sandbar — the Royal Poinciana, with 1,100 rooms, three miles of corridors, and bellhops who delivered messages by bicycle. He built The Breakers on the ocean side. He built a 75-room Gilded Age mansion called Whitehall. He built an entire worker city across the lake. He changed Florida's divorce law to suit his personal life and removed a 2,000-person Black community from the island when it no longer fit his vision. Then an unlicensed architect and a sewing machine heir invented the Mediterranean Revival style that still defines Palm Beach, turning Worth Avenue from a dirt road with an alligator wrestler into the Rodeo Drive of the East. The Florida land boom of the 1920s made fortunes overnight. Two Category 4 hurricanes and the Great Depression destroyed them. The Royal Poinciana was demolished. The Breakers burned twice and was rebuilt in Italian Renaissance concrete at a cost of $7 million. Marjorie Merriweather Post spent another $7 million building Mar-a-Lago — a private home so expensive the federal government later couldn't afford to maintain it. Today, Palm Beach has roughly 9,000 year-round residents, an estimated 70 billionaires, and average home sale prices above $20 million. No American city was ever built on less — and none has attracted more.
