The monastery's founding is attributed to the discovery of a holy icon by shepherds who noticed a light emanating from the Kastri hill.
The name 'Kastriani' derives from the ancient fortress, or 'kastro', that once occupied this naturally defensive position.
The current church architecture is a post-Byzantine structure reflecting Cycladic design influences.
The complex includes a dedicated guest house, a traditional practice for monasteries in the Cyclades to accommodate visiting pilgrims.
It remains one of the most significant pilgrimage destinations in the Cyclades due to the perceived miraculous properties of the icon.
Panagia Kastriani is a 19th-century Greek Orthodox monastery situated on a jagged cliff overlooking the Aegean Sea on the northeastern coast of Kea. The current complex was constructed in 1708 after local shepherds discovered a miraculous icon of the Virgin Mary at the site. The primary church features characteristic blue-domed architecture surrounded by whitewashed monastic cells. It serves as the patron saint sanctuary of the island of Kea. The location is characterized by its exposure to strong northern winds, known as meltemi, which influenced the robust construction of the outer walls. Pilgrims frequent the site during the mid-August feast of the Assumption. The monastery serves as both a religious site and a historical landmark reflecting the island's maritime history.

Ensure your vehicle has a reliable braking system, as the approach involves steep, narrow, and winding coastal roads.
Do not attempt to access the monastery via off-road paths without proper footwear, and avoid visiting during peak heat hours in July and August.
Modest dress covering shoulders and knees is required; silence is expected inside the main church.
