Built in 1917 by John Aspinwall, this extraordinary three-season Maine retreat is among the most beautiful island properties in the Mid-Coast. Set on a peaceful and secluded 95-acre peninsula with 3,809 feet of water frontage, the property offers sweeping views in every direction. A true sailor's paradise, Aspinwall features a new mooring, a substantial deep-water dock, and a granite pier overlooking Flying Passage and Muscongus Bay. The historic main house has been thoughtfully renovated, blending timeless character with modern comfort. Highlights include four bedrooms, a stunning living room with an oak-truss cathedral ceiling and a 12-foot-wide stone fireplace, and a glassed-in sun porch with commanding water views. Multiple decks overlook the private beach, while the primary suite boasts a double-sided fireplace, sitting room, and large en-suite bath. A well-equipped country kitchen with a butler's pantry makes the home ideal for hosting family and friends. In 2007, a large barn was added with a spacious year-round guest apartment above—comfortably sleeping four and offering a private deck overlooking the cove. Two additional shorefront cottages nestle in the evergreens: one a cozy sleeping cottage with a stone fireplace, the other furnished as a charming game room that could easily be converted to additional sleeping space. Sustainable and self-sufficient, the property is served by an artesian well and professionally installed solar, electric, and generator systems—allowing both the main house and guest house to live like homes on the grid. Satellite service provides TV and internet. Offered fully furnished and equipped including a 2019 18' Parker Center Console with 115 Yamaha. This is a rare opportunity to step back in time while enjoying modern comforts. Aspinwall offers boundless possibilities for relaxation, adventure, and unforgettable gatherings.
