The Greek city of Naxos is steeped in mythological mystique and ancient history. The purported home of Dionysus, the Greek god of wine, is fringed with glorious beaches, collisions of turquoise waters and sapphire horizons. The ruins of The Portara frame the sky like a door to another world, while renovated Venetian mansions offer a glimpse into the upper crust of yesteryear. The 13th-century castle is simply breathtaking.
