Olympus Village is the capital city of the Federation on Mars in the Sol system. The Federal Congress and the White House are located there. It replaced its location in Washington, D.C. early in the 3rd millennium.
Terraformed Mars had become a more verdant and comfortable place to live compared to Earth's climate and radiation problems. This caused an exodus of rich and influential people to Mars. Eventually the Federal Congress also moved from Washington, D.C. on Earth to Olympus Village, Mars.
The prestigious university Olympus Village University is located there.
