159 Main Street, Prospect Harbor

Gouldsboro, ME 04669

Set above the waters of Prospect Harbor with sweeping views toward its iconic lighthouse, 159 Main Street is a remarkable Downeast Maine waterfront retreat—offering approximately 570 feet of privately owned shoreline, deep-water access, potential for a seasonal dock and mooring, and the harbor's only beach suitable for launching a boat. Originally dating to 1900, the residence has been thoughtfully renovated and seamlessly expanded while preserving the craftsmanship and New England character of the original home. With approximately 5,300 square feet, four bedrooms, and four baths, the home offers the scale and comfort of a substantial year-round residence, with rich hardwood floors, custom millwork, a dramatic stone fireplace, generous living and entertaining spaces, a chef's kitchen, private office, and two-tier home theater. At the heart of the property is an expansive covered porch overlooking Prospect Harbor. Watch lobster boats cross the working harbor and the tides change beneath the lighthouse, or step down to your own waterfront to launch a kayak or small boat from the beach, with the potential to add seasonal dock and mooring access for even greater enjoyment of the harbor and surrounding coastline. The third-floor primary suite creates a private retreat with beautiful views across the harbor. A heated three-car garage with additional finished space above, whole-house generator, and modern heating and cooling systems add the conveniences expected of a thoughtfully updated coastal residence. Near the Schoodic Peninsula and Acadia National Park, 159 Main Street provides a rare combination of historic New England character, substantial living and entertaining space, and approximately 570 feet of privately owned shoreline with genuine access to the water. Set on more than an acre overlooking Prospect Harbor, it is a property that captures both the beauty of the Maine coast and the character of life along a working harbor.
