How preservation status is recorded
In this guide, preserved means a tower or site retains documented historic fabric, even when condition differs from one location to another.
Access varies by stewardship, safety limits, and shoreline exposure. Some sites are open at set times, some are view-only, and others can be approached only from designated public routes.
Several entries survive in part because storms, erosion, wartime reuse, and later rebuilding changed the original structures over time. Partial remains are included to reflect the full coastal record.
