St. Mary’s is a postcard-perfect jumble of castles and coves. It’s the largest island of the United Kingdom’s Isles of Scilly, an archipelago that’s been inhabited for thousands of years. Ancient stone structures, Spanish windmills, lush gardens and breathtaking wetlands all draw visitors longing for a quaint Cornish holiday that’s steeped in history and modern charm.
