This once-grand Gilded Age villa of the Thousand Islands was constructed in the 1890s for William O. Wyckoff, a tycoon who marketed Remington typewriters. His wife died the month before he moved in, and Wyckoff is said to have died of a heart attack on his first night in this mansion in 1895.
The villa has been vacant for more than 60 years, and it would likely cost millions to restore. The property has been for sale for years, attracting attention from all over the world. The home is listed on HistoricProperties.com, which has a photo of the house in its former glory.
