It is listed in secondary castle compendia and mapping projects as a medieval site and is often recorded as possibly originating in the 11th century. The castle is identified in available reference sources as a Swiss heritage site of national significance, indicating its recognized cultural and historical importance. The supplied source set does not include detailed primary historiography on construction phases, ownership, or specific battles tied directly to the castle, though image indexes in the corpus reference the 1476 Battle of Grandson in broader Swiss historical material. Reported paranormal phenomena are absent from the provided sources: none of the supplied documents, archive metadata, or reference listings describe hauntings, apparitions, named spirits, or other supernatural accounts associated with Grandson Castle. Consequently, no entities, folkloric explanations, or investigative claims are recorded in this dataset. The absence of paranormal material here does not prove the site lacks folklore or local legend, only that such material was not present in the research notes supplied for this entry.
