Glarentza

thumb|Ruins of the church of Saint Francis Glarentza (), also known as or Clarenia, Clarence, or Chiarenza, was a medieval town located near the site of modern Kyllini in Elis, at the westernmost point of the Peloponnese peninsula in southern Greece. Founded in the mid-13th century by William II of Villehardouin, the town served as the main port and mint of the Frankish Principality of Achaea, being located next to the Principality's capital, Andravida. Commerce with Italy brought great prosperity, but the town began to decline in the early 15th century as the Principality itself declined. In 1428, Glarentza was ceded to the Byzantine Despotate of the Morea, and served as its co-capital, being the residence of one of the Palaiologos despots, until the Ottoman conquest in 1460. Under Ottoman rule, Glarentza declined rapidly as the commercial links with Italy were broken, and by the 16th century was abandoned and falling into ruin. Little remains of the town today: traces of the city wall, of a church and a few other buildings, as well as the silted-up harbour.

== History == thumb|250px|Map of the Peloponnese with its principal locations during the late Middle Ages Glarentza was founded in the mid-13th century by William II of Villehardouin (ruled 1246–78), the ruler of the Principality of Achaea, a Frankish state established after the Fourth Crusade and encompassing the Peloponnese or Morea peninsula in southern Greece. Its Frankish foundation is evident in its name, or in French, or in Italian, or in Latin, rendered (Klarentsa), (Klarintza), or (Glarentza) in contemporary Greek documents.
