Preservation notes

This archive records lighthouses as lived coastal places rather than isolated monuments. Entries combine dated photographs, maintenance traces, and local references so each tower can be read in relation to weather, shoreline change, and working history.

Our research approach favors verifiable sources: keeper logs, harbor records, period newspapers, restoration reports, and geotagged field notes. When details are uncertain, the text is marked accordingly so readers can separate documented fact from informed interpretation.

Coverage focuses on surviving northern coast structures with traceable historical continuity. Removed lights and lost sites may appear in context notes, but only preserved towers are indexed as primary records for comparison across districts.

Research Notes

Frequently asked questions

A quick guide to what is documented here, how materials are interpreted, and where the archive boundaries begin.

What kinds of sources inform the lighthouse entries?

Entries are compiled from lighthouse board reports, local harbor records, period newspapers, keeper logs when available, and cataloged image collections from regional archives.

How do you decide which towers are listed as preserved?

A tower is marked preserved when substantial structural fabric remains in place and its status is supported by recent conservation records, municipal listings, or direct field documentation.

Does the map include every lighthouse on the northern coast?

The map focuses on documented northern-coast lights with verifiable coordinates; removed sites and uncertain locations appear in narrative notes rather than as precise plotted points.

How should archive photographs be interpreted?

Captions identify date, collection, and context where known; framing, weather, and exposure can alter apparent scale, so each image is paired with text notes to separate observation from inference.

What historical period does this archive cover?

Coverage begins with early nineteenth-century coastal light establishment and extends to present-day preservation work, with strongest documentation from late nineteenth and twentieth-century service years.
