St. Hilarion Castle looks like it fell straight off the pages of a storybook. With its ramparts climbing up the jagged hilltop, this is the epitome of a fairytale castle (and it's said the castle in Disney's Snow White is based on St. Hilarion).
Built in the 10th century by the Byzantines, the castle sits in a lofty position that has been a strategic asset right up to the modern era.
Follow the path (wear good walking shoes) from the lower enceinte, where the garrison were housed, up to the middle enceinte, with its church and barrack rooms, and then climb higher to the upper enceinte, with a tower and royal apartments.
