Just 25 miles north of Manhattan, THANN Sanctuary Spa at Castle Hotel & Spa is the first of its kind in the United States. Known throughout Asia as an oasis of peace and tranquility, THANN offers a wide variety of luxurious spa treatments based on the art of natural therapy, where all the senses are awakened by the unique holistic spa concept and ambience.
The stunning architectural design of the spa gracefully emerges from the serene wooded landscape in a simple yet sophisticated building that utilizes stone walls and minimal exterior openings to blend with its peaceful setting. A massive stone wall guides the guest through an opening into a sheltered interior courtyard. The walls flanking the courtyard are transparent floor-to-ceiling glass creating a contrast with the solid stone wall exterior.
