Perched above the bucolic rolling hills of Millbrook Hunt Country, framed by panoramic views of the Catskill mountains sits an idyllic country retreat and extraordinary equestrian estate encompassing 185 ultra-private acres. Once the cherished estate of Margaret Carnegie, only child of Andrew Carnegie, a rich legacy of elegance and prestige is preserved and embraced throughout this iconic property. Originally constructed in 1865 has been thoughtfully expanded with sophisticated living spaces and abundant opportunities to entertain throughout. This residence masterfully unites historic grandeur with modern luxury, and the warmth and charm of yesteryear. The main residence showcases timeless refinement: a richly paneled library with cozy fireplace, an elegant formal dining room to host 30 of your dearest guests, and a grand living room with soaring ceilings and French doors opening to the terrace to watch the sunset and the everchanging views of the Catskills. At the heart of the estate, a world-class equestrian facility designed by acclaimed French architect Atelier Choiseul features state-of-the-art stables, paddocks, a tack room, staff housing, and a refined lounge. A hunter trial course completes the unparalleled amenities for horse enthusiasts. With miles of fenced pastures, private riding trails, sparkling ponds, and unmatched tranquility is just minutes from the Village of Millbrook and within 90 minutes of Manhattan. The magnificent grounds and estate's vast acreage allows for the quintessential pastoral experience, and leave ample room for additional recreational pursuits. This ultra-private retreat offers the best of both worlds: the sophistication of country living alongside access to the Millbrook Hunt, Mashomack Polo, Sandanona and the region's most prestigious pursuits. With 185 acres, this turnkey estate also presents endless possibilities to expand whether designing new equestrian amenities, or shaping the land into a visionary retreat tailored to future generations. This is more than a residence, it is a legacy property offering unmatched privacy, historic provenance, and the ultimate expression of Hudson Valley luxury ready to elevate the sense of exclusivity.
