Kallikratis (Greek: Καλλικράτης) is a small village in Sfakia municipality, southwest Crete, Greece. According to tradition, it was named after the admiral (droungarios) Manoussos Kallikratis, who in March 1453 led a campaign to reinforce the defense of Constantinople with 5 ships and 1500 Cretan volunteers. As reported by Sphrantzes in his Chronicle, these volunteers manned three towers on the walls of Constantinople and continued to fight bravely even after the city had fallen.
