Wikiosco | A Historic Lake George Legacy Estate Wikiosco, a rare offering on the western shore of Lake George, is a distinguished historic estate listed on the National Register of Historic Places. Commissioned in 1895 by industrialist Royal C. Peabody, a founder of the famed 'Millionaire's Row,' it remains one of the few surviving grand residences from Lake George's Gilded Age. Its name, meaning 'home on beautiful waters,' reflects its exceptional setting on 6.3 private acres with approximately 560 feet of pristine shoreline. The Tudor Revival residence features a rough-cut granite facade, sweeping lakefront terraces, and elegant formal rooms that embody the craftsmanship of its era. Carefully maintained and enhanced, the home preserves its historic character while offering modern comfort. A tree-lined drive leads to a porte-cochère entrance and a residence featuring seven bedrooms and adjoining baths, private sitting rooms, library, billiard room, two full bars, exercise room, sauna, steam room, and locker rooms. A 4,000-bottle wine cellar supports both collectors and entertaining. The grounds offer exceptional amenities, including a saltwater pool, tennis, pickleball and basketball court, and garage space for up to 21 vehicles with additional storage. At the waterfront, a six-boat docking system, including two covered slips, provides direct access to the beauty and recreation of Lake George. A restored former icehouse serves as a charming two-bedroom guest cottage. The estate also benefits from a lake-fed sprinkler system and a unique history as both a bed-and-breakfast and restaurant. Included in the offering is the adjacent 1.4-acre parcel at 3234 Lake Shore Drive with a separate three bedroom residence, providing flexibility for guests or staff. More than a lakefront home, Wikiosco is an irreplaceable piece of Lake George history, combining architectural significance, expansive waterfront, and outstanding amenities in a true legacy estate.
