Dundas Castle in Roscoe, NY is considered haunted due to its abandonment and several urban legends, including tales of a seductive woman from the 1930s and the ghost of Josephine Dundas, who some believe was locked away in the castle. The three heart-shaped ponds on the property are also a focal point of the legends, with stories claiming they fill with blood on the full moon. While the castle was built for a wealthy owner, neither he nor his wife ever lived there, contributing to its mysterious and abandoned atmosphere. One recurring legend claims the castle is haunted by the ghost of Josephine Dundas, the wife of the original owner. Some versions of the story suggest she was confined to an upstairs room due to her mental health issues. Another legend speaks of a beautiful, long-haired woman from the 1930s who lured fishermen to the castle for a pleasant adventure or perhaps worse. The property features three heart-shaped ponds, and the legend states that their waters turn to blood during a full moon.
