Ellis Island
island in New York Harbor in the United States of America
Ellis Island is an island in New York Harbor, within the U.S. states of New Jersey and New York. Owned by the U.S. government, Ellis Island was the busiest immigrant inspection and processing station in the United States. From 1892 to 1954, about 12 million immigrants arriving at the Port of New York and New Jersey were processed there; according to one estimate, two-fifths of Americans may be descended from these immigrants. It has been part of the Statue of Liberty National Monument since 1965 and is accessible to the public only by ferry. The north side of the island is a national museum of immigration, while the south side of the island, including the Ellis Island Immigrant Hospital, is open to the public through guided tours.
The name derives from Samuel Ellis, a Welshman who bought the island in 1774. In the 19th century, Ellis Island was the site of Fort Gibson and later became a naval magazine. The first inspection station opened in 1892 and was destroyed by fire in 1897. The second station opened in 1900 and housed facilities for medical quarantines and processing immigrants. After 1924, Ellis Island was used primarily as a detention center for migrants.

Why this record matters
The phrase “island in New York Harbor in the United States of America” supplies a clear boundary for inquiry. It also exposes the unanswered questions: who defined that boundary, when it became stable and which sources sit outside it.
Maps, plans, fabric surveys and administrative records can establish how the site’s name, extent and function changed over time. The source revision retrieved here is dated Sep 24, 2026. The linked authority identifier is Q202175. The first chronological checks are 1892, 1954, 1965 and 1774.
Architectural summaries often privilege surviving fabric and can understate demolished phases, contested use or displaced communities. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
