Kastro Sifnos is one of the most historic and scenic villages on the island. It sits on a rocky hill along the eastern coast and faces the Aegean Sea on three sides. This strategic location offered protection for centuries. The name “Kastro” means “castle” and reflects the area’s role as a fortified settlement. It served as the island’s capital until the 19th century.

Narrow stone alleys wind through the village, flanked by whitewashed houses with arched doorways and ancient details. Many of these buildings date back to the 16th century. The architecture blends Venetian and Cycladic styles, creating a unique atmosphere. Each step leads to hidden courtyards, marble columns, and carved coats of arms that hint at the village’s rich past.

Over ten small churches lie within the village walls. Many feature stone bell towers and traditional blue domes. One of the most famous churches in the area is the Church of the Seven Martyrs. It stands on a rock just below Kastro. A narrow stone path leads down to the church. Along the way, visitors enjoy sweeping views of the sea and cliffs. 

Remnants of a prehistoric acropolis rest beneath the current village. Archaeologists have discovered pottery, tools, and foundations from ancient times. Some of these artifacts appear in the local archaeological museum. Although small, the museum provides a good overview of Kastro’s long history.

Despite its peaceful appearance, Kastro offers a lively charm. A few cozy cafés and art shops line the walkways. Small tavernas serve traditional food and cold drinks. During sunset, the light casts golden tones over the village and sea. 

Kastro Sifnos offers more than beauty. Its walls, churches, and views tell stories of a different time. Every corner holds history, peace, and a deep connection to the island’s soul.
