Patras is the third largest city of Greece, and the capital of the Achaea prefecture of Greece and of the Region of West Greece.
The first traces of settlement in Patras date to the 3rd millennium BC, in modern Aroe. During the Middle Helladic period (the first half of the 2nd millennium BC), another settlement was founded in the region. Patras flourished for the first time during the Post-Helladic or Mycenean period (1580–1100 BC). Ancient Patras was formed by the unification of three Mycenaean villages located in modern Aroe, Antheia and Mesatis. Mythology tells us that after the Dorian invasion, a group of Achaeans from Laconia, led by the eponymous Patreus, established a colony. During antiquity, Patras remained a farming region but in Roman times it became an important port.
Today Patras is considered to be one of the most beautiful towns in Greece and is popular with tourists.
