Longwood Estate presents a rare opportunity to create a distinctive waterfront event venue on 20± acres overlooking West Penobscot Bay. With 679± feet of shorefront, elevated views toward Islesboro and the Blue Hill Peninsula, and a landscape combining open fields, mature woodland, stone walls, gardens, and winding paths, the property offers a naturally memorable setting for gatherings of many kinds. The property includes a 4,000± square-foot level terrace with a substantial retaining wall and an expansive 18,000± square-foot lawn overlooking the bay. These spaces offer exceptional flexibility for ceremonies, tented receptions, cocktail gatherings, dining, entertainment, or other programming, with the potential to create multiple distinct experiences across the property. The current owner has Maine DOT approval for up to 50 vehicles for commercial use, and there are utilities in place near the terraces. A fully renovated two-bedroom cottage provides comfortable year-round accommodations, while a carriage house with a three-car garage and two-bedroom apartment offers a space to be renovated to suit your needs for guests, staff, parties, or venue operations. Multiple potential building sites further expand the possibilities for future event, hospitality, or support facilities. Accessed through a graceful stone-pillared entrance and set well back from U.S. Route 1, Longwood Estate combines privacy, scale, and dramatic coastal scenery while remaining convenient to Belfast, Lincolnville, and Camden. The estate offers an unusually versatile waterfront setting with significant potential as a private-event property, retreat center, or other hospitality-oriented uses.
