Fortress Explorations is Tokyo Disney Sea's version of Tom Sawyer Island on steroids--a large scale exploration area that immerses guests into a Renaissance-era fortification, including its own Age of Exploration sailing ship moored in Mediterranean Harbor.  Overlooking the main side of Mediterranean Harbor gives it lovely vistas and an especially escapist feel, and its different approaches all seem to carry scenic compositions and beautiful settings.  This angle below, for example, feels incredibly escapist, and its marvelous details are wonderfully immersive.  It's just another in countless cases of why this is the "Sea of Dreams." The Renaissance sailing ship anchors Fortress Explorations at Tokyo Disney Sea.
