TLDR
Between 1892 and 1954, over 12 million immigrants passed through Ellis Island into the U.S. More than 3,500 people died on the island during that period, including 420 between 1909 and 1911 — 85% of them children under 13. The abandoned hospital buildings are the most active area.
The Full Story
The hospital complex on Ellis Island is one of the most active locations in New York for paranormal investigators. Doors open and close on their own, furniture gets rearranged overnight, and the sounds of children's voices echo through empty wards.
Certain rooms get noticeably colder for no reason, and some visitors have described feeling suddenly ill or experiencing brief moments where they seemed to lose control of their own body. People have seen figures in period immigrant clothing walking the halls -- the ghosts of those who died just short of reaching America. The hospital areas, which are closed to regular tourists but opened for special tours, generate the most reports.
