Oia's Castle Verified listing

Oia’s Castle, also known as the Castle of Agios Nikolaos, is one of the most iconic viewpoints on the island of Santorini, located in the picturesque village of Oia at the island's northern tip. Originally built in the 15th century by the Venetians to defend against pirate attacks, the castle played an important role in the island’s medieval history. Although much of the structure was destroyed during the 1956 earthquake, parts of the ruins remain intact, offering a dramatic setting that blends history with natural beauty.

Today, the castle is most famous as a sunset viewpoint, attracting crowds each evening who gather to watch the sun dip below the horizon and cast golden hues over the caldera and whitewashed buildings of Oia. The view from the ruins is truly breath-taking and has become one of the most photographed spots in Greece. The combination of ancient stone walls, dramatic cliffs, and the glow of the setting sun creates a scene that feels almost unreal—ideal for photographers, couples, and travellers seeking that quintessential Santorini experience.

There is no entrance fee to visit Oia’s Castle, and it's open to the public at all hours, though it’s best to arrive early in the evening to secure a good spot for sunset. Comfortable shoes are recommended, as the walk through Oia’s narrow pathways and up the steps to the castle can be steep and crowded. While there are no facilities at the castle itself, Oia offers plenty of nearby cafés, shops, and restaurants to explore before or after your visit. For anyone visiting Santorini, watching the sunset from Oia’s Castle is an unforgettable highlight.
