About this lighthouse

The U.S. Coast Guard lists Grindel Point 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.

The structure is recorded in the National Register of Historic Places. A National Register listing documents historic significance. It does not mean the public can visit.

Awaiting verification: Wikidata gives 1850 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.
