Old Navarino Castle

The Old Navarino castle (Greek: Παλαιό Ναυαρίνο) is a 13th-century Frankish fortress near Pylos, Greece. It is one of two castles guarding the bay on which it sits; the other is the Ottoman-built New Navarino. It is frequently known simply as Palaiokastro or Paliokastro (Greek: Παλαιόκαστρο or Παλιόκαστρο, "old castle"). It occupies the site of the Athenian fort at the 425 BC Battle of Pylos.
