Nestled at the western edge of Martha's Vineyard, where the landscape opens, the pace slows, and the light takes on a character all its own, lies Aquinnah-one of the island's most treasured and unspoiled destinations. Known for its iconic clay cliffs, rolling landscapes, and exceptionally limited year-round population, Aquinnah offers a level of privacy and natural beauty rarely found today. Set within this remarkable setting, 19 Locust Lane represents an extraordinary offering. Encompassing nearly 17 acres perched high above Vineyard Sound, this rare compound-scale estate captures sweeping water views extending to the Elizabeth Islands and beyond. Opportunities of this scale and significance seldom come to market in Aquinnah. Designed for both grand entertaining and multi-generational living, the property includes a main residence and separate guest house, thoughtfully constructed in 2005 and unified by timeless architectural details including cedar shake siding and stone walls that blend naturally into the surrounding landscape. Inside, the 6 bedroom home is warm with sophisticated interiors featuring wide-plank floors, Gourmet Kitchen with Tuscan oven, an expansive open-concept dining area, and a dramatic great room with soaring cathedral ceilings, exposed cedar trusses, and a striking floor-to-ceiling stone fireplace-all perfectly oriented toward the breathtaking ridgeline and water views beyond. Aquinnah remains one of Martha's Vineyard's most authentic and untouched landscapes. 19 Locust Lane offers a rare opportunity to experience its beauty, privacy, and enduring character on an extraordinary scale.
