Gibson Atherton, the home’s builder, was an early mayor of Newark, serving from 1860-1863. Additionally, Atherton served two terms in the US Congress in 1878 and 1880.  After the Athertons, The Castle was the home of James Lingafeller. It was also later owned by Claude Davis, Dr. Victor Turner, and finally Cosmo Investors. 
In 1952, the decision was made by its owner, Cosmo Investors, to demolish the nearly-100-year-old structure. A fire had damaged some of the building and the company was in need of a parking lot, so the company opted to demolish the residence. 
The site of The Castle is now a portion of the parking lot of the DoubleTree Hotel in downtown Newark.
