Built in Greece in the 13th century by the Franks, this site was once an important observation place. Its strategic location made it a prime spot for protecting the bay. As such, it endured centuries of attacks and sieges.

The Venetians gained control of the fortress in the 15th century, but it wasn’t long before the Ottomans attempted to stake their claim to the castle. The fortress passed back and forth between Venetian and Ottoman hands before the Ottoman forces eventually proved successful.

However, after the construction of Pylos castle nearby, Navarino lost its significance and gradually began degenerating. It is now commonly referred to by the locals as Paleokastro, meaning “the old fortress.” Today, only fragments of it still stand.

Though the castle is a mere skeleton of its former glory, it’s still worth visiting. From the top of the cliffs it crowns, you will have stunning panoramic views of Voidokilia Beach, the lagoon, coastline, and nearby islands. You’ll also find Nestor’s Cave halfway up the rock formation. Although the cave is not too deep, it is still worth taking a flashlight and exploring.
