Incredible natural beauty defines the Millbrook School campus which is located 90 miles north of New York City (Dutchess County) in the lovely countryside of the Mid-Hudson Valley region. Its rural 800 acres contain rolling hills, forests, wetlands, playing fields, trails (used by those on foot or on horseback) and the campus proper which is arranged around the main quadrangle.
The quad is reminiscent of a traditional New England village with the Flagler Memorial Chapel at its head and red brick and white clapboard buildings completing the square. There are also eight dormitories, the Schoolhouse, the Dining Hall, the Mills Athletic Center, the Holbrook Arts Center, the Frederic C. Hamilton Math and Science Center, Pulling House (the head of school's residence), the Barn (completely renovated in 2012, home to the student center and college counseling), and the six-acre Trevor Zoo.
