Oia, pronounced “Ia”, is the most famous of all the small villages of Santorini. It’s also the most picturesque. At the northern crescent tip of the island, Oia is a traditional village of beguiling houses terraced up a hill, narrow laneways, blue-domed churches and sun-bathed verandas all overlooking the Caldera. A world away from the tat-filled, tourist-clogged streets of Fira it’s here in this idealized version of Greece that I understand why so many people feel drawn to Santorini.
