The archive documents lighthouse history along the northern coast, including tower timelines, preservation status, keeper records, and regional maritime context used by researchers, students, and visitors.

The map groups towers by coastal segment and present condition, helping readers compare active aids, preserved structures, and interpreted sites while moving from geography into deeper records.

“Preserved” refers to towers or associated structures that still physically exist, are documented in stewardship records, or are maintained through conservation, adaptive reuse, or formal heritage protection.

Stories are curated from verified logs, letters, oral histories, and local publications, then edited for clarity while preserving historical context, attribution, and place-based accuracy.
