Mythical locations are places that exist in folklore, legends, and stories but are not found on any real map. Examples include Atlantis, a lost underwater city said to be advanced and powerful, and El Dorado, a legendary city of gold sought by explorers. These locations often symbolize human desires, such as wealth, knowledge, or adventure. Many cultures have their own mythical locations, like Avalon in Arthurian legend, a paradise where King Arthur is said to rest. These places often serve as settings for epic tales, reflecting the values and beliefs of the societies that created them.
