New Navarino Fortress
Municipality of Pylos-Nestor, Greece
The fortress of New Navarino (Ottoman Anavarin-i cedid) is an Ottoman fortification near Pylos, Greece. It is one of two castles guarding the strategic Bay of Pylos, on which it sits; New Navarino is located in the southern entrance of the bay, while the northern entrance is guarded by the 13th-century Old Navarino castle, built by the Crusaders of the Principality of Achaea. In juxtaposition with the latter, New Navarino is often known simply as Neokastro or Niokastro ("new castle").
