About
About Kyllene-Glarentza – Frankish Medieval Harbour of Elis
Kyllene was the Classical port of Elis serving Olympia (Homer Iliad, Strabo, Pausanias); its medieval successor Glarentza was the mint and chief port (1205–1428) of the Frankish Principality of Achaea. Classical and Crusader harbour installations overlap: north of the medieval town walls, rubble moles, ashlar quays and submerged anchorage blocks extend into the sea at −1 m to −5 m, mapped 2013–18 by the Greek Culture Ministry and Patras University Oceanus Lab (Papatheodorou, Geraga).
The visible basin is now backfilled, but geophysics traced the Crusader pier (c. 80 m) built atop Classical Kyllene blocks. Classical Kyllene was a trireme base; Glarentza coined tornesi for the Morea. Abandonment after 1428 Ottoman pressure and harbour silting.
Why it mattersOnly stratified Classical→Frankish harbour in Greece showing reuse of ancient mole as medieval pier; links Olympia supply network to Crusader Morea coinage.
