This is the highest point in the Keys, though at 16 feet above sea level it's not likely to give anyone altitude sickness. Originally two islets, this area was first inhabited by American Indians, who left behind a few traces of their dwellings, and then by farmers and fishermen who built their homes here in the mid-1800s. Henry Flagler bought the land from homesteaders in 1908 for his Florida East Coast Railway, filling in the inlet between what were then called the Umbrella
Keys. His workers quarried coral rock for the rail bed and bridge approaches—the same rock used in many historic South Florida structures, including Miami's Vizcaya and the Hurricane Monument on Upper Matecumbe. Although the Quarry Station was destroyed by the 1935 hurricane, quarrying continued until the 1960s. Today, this is where you'll find Theater of the Sea, the famous Holiday Isle (now Postcard Inn), and Windley Key Fossil Reef Geological State Park.
