Reviewed 6 September 2026 · Santorini (Thera), Cyclades, Greece

Why Santorini has castles

Fortified settlements developed in response to insecurity and pirate raids. Their compact lanes and defensive positions remain visible today.

Best preserved experiences

Emporio and Pyrgos are particularly rewarding for walking through historic fortified fabric; Oia’s castle ruins are famous for sunset views.

Skaros Rock

Skaros near Imerovigli preserves the dramatic setting of a former fortified settlement. The route involves steps and exposed terrain.

Practical visit

Combine castles with their surrounding villages rather than rushing between them by car. Early morning is quieter and more comfortable in summer.
