About this lighthouse

The U.S. Coast Guard lists Deer Island Light in its current Light List as an aid to navigation. Light List entries describe the light for mariners; they do not say whether the site is open to visitors.

Awaiting verification: Wikidata gives 1890 as the year this station or structure was established. We have not yet confirmed this against a primary source, so it is not shown as a fact. See the Wikidata lead.
