Oia Castle, also known as the Kastro of Oia, is the ruin of a medieval fortress on the northern tip of Santorini in the South Aegean, Greece. The site sits at the edge of the village of Oia, with the postal address Oia 847 02, and it is one of the island's most photographed spots.
What a visit is like
The castle is mainly a place to walk and look. What remains of the fortress ruins stands above the village, and from its vantage point the view opens across the Aegean Sea. It is the sunset that draws most visitors, as the sky and water change colour over the caldera and the white village around you.
- Best suited to visitors who enjoy walking among old stone ruins and open views
- Popular at sunset, so expect company on the walk up and at the top
- Comfortable footwear is useful, as the approach is over uneven ground
Around the castle
Oia itself is a good reason to stay in the area after your visit. The village's narrow lanes, whitewashed buildings and blue-domed churches are a pleasant place to wander, and many of its cafรฉs and terraces face the same sea view. Allow time to explore on foot before or after the sunset.
