With two impressive towers and a stone exterior, this magnificent mansion, completed in 1910, sits amid 11 hilltop acres overlooking the Hudson River and was modeled after Lismore Castle in County Waterford, Ireland. The main tower is the highest point in Westchester County. Rooms occupy the original house and a stucco wing, where you'll also find the THANN Sanctuary Spa that offers holistic spa treatments. Rooms are elegant, decorated with antiques, silk curtains, and
four-poster beds. The food at the Equus restaurant is as refined as the surroundings.
