Uranopolis or Ouranopolis was a city in the Chalcidice in ancient Macedonia, allegedly founded by Alexarchus, brother of king Cassander of Macedonia. Uranopolis was the site of a mint in the Kingdom of Thrace. Coins of Uranopolis are known for displaying Athena or the Muse Aphrodite Urania, the muse of astronomy, sitting on a globe. The globe represents the Celestial Sphere. It is a common misunderstanding that the globe represents the earth and that this is the first known depiction of the earth in its actual shape.
