Kastro is the largest settlement on the island of Sikinos and one of the two main settlements of Chora. The two settlements are spread on two opposite mountain slopes. Kastro is built on the edge of a cliff 280 meters above the sea and is a fortified settlement of the 15th century with narrow alleys, low whitewashed houses, arcways and flowered courtyards. All these make Kastro the oldest and most picturesque village on the island.
Here beats the island's heart : the paved square, the town hall, the doctor's office, the shops and the cafes are the core of the island's social life. Wander around to discover old stone mansions, the golden-painted wood-carved temple in the church of Pantanassa and old icons at the Byzantine Collection. The church of Pantanassa is also the landmark of the village. In the square there is the Paraporti, where it is the only surviving part of the old castle.
From Kastro begins a paved path that leads to the monastery of Chrysopigi (Zoodochou Pigi) of 1690, at the top of the village. The view to the Aegean that you will enjoy from the monastery is unique. From Kastro you can also walk to Chorio, the second and equally picturesque settlement of the island.
