Astypalea Castle, the white fortress suspended between sky and sea in Greece

There are places that seem to have been drawn by a painter in love with the Aegean Sea, and the Castle of Astypalea is one of them. Imagine a white fortress perched on the island's highest hill, with stone walls that seem to blend with the sky and the blue roofs of the Orthodox churches that emerge like luminous gems. It is the absolute symbol of the butterfly-shaped island , a blend of legend, Venetian history, and Cycladic charm that captivates at first sight.

Astypalea isn't the picture-perfect Greece everyone knows: it's wilder, more intimate, and authentic. And for this very reason, its medieval castle, also known as the Querini Castle , seems even more magical. It's stood there for centuries, guarding Chora, ready to tell tales of pirates, knights, and ancient lords. But visiting it today is an experience that transcends history: it means walking among ruins suspended between sky and sea, breathing in the salty wind, and feeling part of a timeless landscape.

What to see at Astypalea Castle

Once you reach the top, the view is breathtaking: on one side, the Aegean stretching into infinity, on the other, the white labyrinth of Chora, with its narrow alleys and Cycladic houses. The Querini Castle was built by the Venetians in the 15th century to defend the island from pirate attacks. Today, its mighty walls remain, along with several towers and the two churches that steal the show: Panagia Kastrou and Agios Georgios , both whitewashed with classic blue domes that contrast with the dark stone of the fortress.

Wandering among the castle ruins in Greece is like stepping into an epic film: you pass carved Gothic portals, half-destroyed arches, and courtyards that once bustled with life. Some vantage points are veritable balconies overlooking the Aegean, perfect for sunset photos when the sky glows orange and pink.

The magic, however, lies not only in the architecture. It's the atmosphere that strikes: silent, suspended, with the wind whistling through the stones and the sound of the sea in the distance. Visiting the castle at sunset is a thrilling experience: in that moment, it truly feels as if time stands still.

What to do around Astypalea Castle: the Chora and the windmills

After visiting the fortress, one of the most beautiful in Greece, we recommend exploring Astypalea's Chora , which begins right at the foot of the castle. Its whitewashed houses are arranged like an amphitheater rising up the hill, and strolling through the narrow streets is a constant interplay of picturesque views, colorful staircases, and fuchsia bougainvillea exploding between the facades.

Descending toward the main square, you'll be greeted by the iconic eight windmills , lined up like little red and white guardians. They're the beating heart of the city's nightlife: here you'll find bars, taverns, and clubs that, as the sun goes down, fill with music and chatter.

Another unmissable experience is climbing the castle at night, when the fortress is illuminated and the island, the westernmost of the Dodecanese and geographically considered part of the Cyclades , sinks into silence. From the summit, the starry sky seems closer than ever: Astypalea, thanks to its low artificial lighting, is a paradise for astrophotography enthusiasts.

Practical tips for visiting Astypalea Castle

The castle is easily reached on foot from the main square of Chora: the climb is steep but short, and offers spectacular views along the way. There is no entrance fee, and the visit is free , but it's a good idea to wear comfortable shoes because the ground inside is uneven. The best time to visit is undoubtedly sunset, when the warm light paints the walls golden. Bring water and a light jacket: even in summer, the wind can be quite strong up there.
