Lighthouses of the World
For centuries, lighthouses have guided ships safely past rocks, shallows and stormy headlands. Every lighthouse has its own signal: a pattern of flashes that tells sailors exactly which light they are looking at.
This guide takes you to five remarkable lighthouses: the Tower of Hercules in Spain, Peggy’s Point in Canada, Fanad Head in Ireland, Nugget Point in New Zealand and Kõpu in Estonia.
How to use the app: open a lighthouse to watch its signal and count the flashes, collect a stamp in your passport for every visit, then test your memory and your eye in the games.
