What do Cleopatra, the man who blew up the Parthenon, Greek Prime Minister Mitsotakis, and Turkey’s President Erdoğan have in common? A shared interest in a tiny Mediterranean island. Kastellorizo, population 500, is only 4.6 square miles in area but it has the unlikely official name of The Biggest (Megisti), which it is, compared to the smaller islands beside it. Although photogenic enough to be the site of the delightful film Mediterraneo (1991), Kastellorizo is coveted for its geostrategic importance.
