Is there really a city made of gold somewhere in South America?

Eldorado was one of many mythical regions of great riches. The search for Eldorado led to the rapid exploration and conquest of much of the Americas by Spaniards and others. Since then, Eldorado has come to mean any place where wealth can be quickly and easily gained. The story is often mentioned in literature, as in Milton’s Paradise Lost and Voltaire’s Candide.
