The ʻIolani Palace was the royal residence of the rulers of the Kingdom of Hawaii. It is now a National Historic Landmark listed on the National Register of Historic Places.
It is reputedly haunted by the ghosts of a figure in black 19th century dress; a young Hawaiian girl; unusual lights and shadows.
A piano in the Blue Room plays of its own accord and inexplicable wet footprints have been found in the hallways.
