Perched on a hill overlooking the sea, Kastro is the most picturesque village on the island of Sifnos. It boasts narrow alleyways, traditional Cycladic houses, and stunning sea views.
The village is named after its Venetian-era castle, remnants of which can still be seen. While here, don’t miss a visit to the breathtaking Church of the Seven Martyrs, perched on a rocky outcrop above the Aegean.
