Castle of Oia

How to Visit Oia, Greece

"I visited Oia Castle, also called St. Nicolas Castle, to get a sense of Santorini’s history; though little of the original fortress remains, you can still spot rubble from the 15th-century watchtower that once defended the island, and the site provides a sweeping ocean view that has made it the most popular—and often crowded—spot to watch the sunset." - Stacey Leasca Stacey Leasca Stacey Leasca is an award-winning journalist and co-founder of Be a Travel Writer, an online course for the next generation of travel journalists.
