Paxi or Paxoi ( Greek: Παξοί, pronounced in English and in Greek) is the smallest island group within the Ionian Islands (the Heptanese). In Greek it is a plural form. The largest islands are Paxos and nearby Antipaxos. Antipaxos is famous for its wine and two of the finest sand beaches in the Ionian Sea. The main town of Paxoi, and the seat of the municipality, is Gaios. In Greek mythology, Poseidon created the island by striking Corfu with his trident, so that he and wife Amphitrite could have some peace and quiet.
