Est. 1875 · Gilded Age Architecture · Marine Biologist Legacy · Newport History · Architectural Preservation
The mansion on Castle Hill was commissioned in 1875 by Alexander Agassiz, a prominent marine biologist, naturalist, and professor at Harvard University. The Gilded Age construction, designed by architect Robert H. Slack, created a palatial summer residence overlooking Newport's coastline. The property remained within the Agassiz family throughout the 19th and early 20th centuries.
The great hurricane of 1938 significantly altered the property's isolation, creating environmental barriers that traumatized the family. Maximilian Agassiz's daughter-in-law became so terrified by the storm's aftermath that she abandoned the property. During World War II, the mansion temporarily served as a naval base. Subsequent to the war, the property was converted into a luxury inn, maintaining the original architecture while accommodating hotel operations. Contemporary operations as Castle Hill Inn have attracted celebrity guests and paranormal interest communities.
Sources
Paranormal phenomena at Castle Hill Inn center on a female entity believed to be an Agassiz family member, with some accounts extending to include Alexander Agassiz himself. The primary manifestation involves poltergeist-type activity—specifically, china and dishware being thrown or displaced within the pantry area. Staff and guests have documented these kinetic phenomena over extended periods, suggesting either residual haunting or intelligent entity engagement.
The specificity of the manifestation location (pantry) and object type (china) suggests possible connection to kitchen staff, food service operations, or household management activities historically associated with female family members or household staff. The repeated nature of the phenomena across decades of inn operation indicates consistency in paranormal manifestation pattern rather than isolated incidents.

Its first event, two weeks after opening, was the inaugural ball for Texas Governor Sul Ross. Driskill sold the hotel in 1888 after severe drought devastated his cattle herds and died in 1890.
