There's a majestic estate standing on the tip of Carleton Island near Cape Vincent in the Thousand Islands. Its beauty and grandeur still shine although you can see the years of neglect eating away at the structure.Before the famous Boldt Castle and Singer Castle were built on the islands, there was Carleton Island Villa built in 1894. Also known as Wyckoff castle, the home has not been lived-in for more than 70 years. Although set behind a barbed wire fence, its once Gilded Age glory continues to fascinate those cruising nearby on the waters.
