Mr. Gillette had nothing to do with the razor blades; he was a well-known Sherlock Holmes actor in the early years of the film. He used the money he earned from this to have this replica of the castle built. He must have been quite playful, as there was a small steam train in the garden that transported guests (the locomotive is in the information center).

Built between 1895 and 1899, Hearthstone Castle is listed on the National Register of Historic Places. It was originally built for E. Starr Sanford. It then changed hands several times before being bought by the City of Danbury in 1987. The castle has now fallen into disrepair and the roof collapsed. You cannot enter the castle, but it is a very interesting site to see how nature has reclaimed the building.
