Welcome to Redstone Castle, a turn of the century jewel completed in 1902 for industrialist and coal magnate John Cleveland Osgood. At the time, Osgood was one of the wealthiest people in the United States, purportedly ranking sixth. It is also known as Cleveholm Manor, its original name. The Castle anchors the mountain hamlet of Redstone, in the magnificent Crystal River Valley still dominated by beautiful, wide-open spaces and undisturbed nature. Placed on the National Register of Historic Places in 1971, the Castle provides a unique glimpse into the personal styles and social culture of America’s elite at the turn of the 20th Century.
