About this lighthouse

The U.S. Coast Guard lists Southwest Ledge Light in its current Light List as an aid to navigation, describing the structure as “White octagonal house on brown cylindrical pier”. 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 1877 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.
