Megalonisi (Greek: Μεγαλονήσι), also Nisiopi (Greek: Νησιώπη), is a long island near the west coast of the island Lesbos, North Aegean, Greece.[1] It is situated in front of Sigri's harbour, and stretches across the mouth of the bay and acts as a buffer to the prevailing winds. In the middle stands Megalonisi Lighthouse to help ships navigate in the rough east Aegean Sea.[2][3]
