The island was spotted by Christopher Columbus on his third New World voyage on 12 August 1498, and his little fleet spent the night anchored in Monkey Harbour. He named the island 'Port of Cats' because he heard roars of what he thought were wildcats, mistaking the call of howler monkeys for wildcats. It has also been called "El Caracol" (the Snail) because of its shape. At various times in its history Chacachacare has served as a cotton plantation, a whaling station and a leper colony.
