The archive covers documented lighthouse sites along the northern coast, emphasizing historical development, operational periods, and preservation status rather than complete maritime infrastructure records.

Terms such as preserved, adapted, and fragmentary describe physical condition and continuity of original structure; they do not indicate public access, ownership, or restoration quality.

Captions pair each image with approximate date, viewpoint, and known source conditions so visual details are read as historical evidence, not as isolated aesthetic scenes.

Stories are curated from letters, log references, oral history excerpts, and local records, then edited for clarity while preserving named dates, places, and documented uncertainty.

Start with marker type and status labels, then compare shoreline position, station dates, and nearby references to understand both where a tower stands and how its role changed over time.
