There is a town at the end of Martha's Vineyard. The road narrows, the houses thin, and the light changes. This is Aquinnah — the westernmost town, clay cliffs, a lighthouse, and one of the smallest year-round populations on the Vineyard. Compound-scale offerings rarely come to market here.19 Locust Lane is one of them.Nearly 17 acres high above Vineyard Sound, with open water views to the Elizabeth Islands. A custom Dutch Colonial main residence and separate guest house, both built in 2005. Cedar shake. Stone walls. Built to belong to the landscape, not compete with it.Inside: over 6,000 square feet across six bedrooms. Wide-plank floors, an open-plan dining room, and a gourmet kitchen with a Tuscan oven. At its center, a great room with cathedral ceiling, cedar trusses, and a floor-to-ceiling stone fireplace, facing the ridgeline and water beyond.Room to host, with the flexibility of two living spaces.Aquinnah has kept its character. This is the place that lets you stay there.
