Lighthouse Notes, from the edge of the land

Field notes

The atlas records details such as height, dates and light characteristics, and offers browsing by coast. Separate sections collect keeper stories, travel notes and a signal demo that lets readers select a characteristic and watch its rhythm. The homepage reports 118 visits across 21 countries, 19,870 steps climbed and three nights spent in a keeper’s room; Holt says entries are corrected when readers write in.
