An interactive map of all 140 Spanish lighthouses has been created by cartographer Aaron Becker as part of his Mapped Earth project. The map displays Spain's coastline in darkness, illuminated only by the rhythmic flashes and rotating beams of each lighthouse, accurately mimicking their real-life light patterns.
This isn't just a pretty visualization: in the real world, each lighthouse's unique flash pattern allows sailors to identify their location along the coast. The map brings that navigational aid to life, offering a stunning and educational view of Spain's maritime heritage.

What the Map Shows
The map covers the entire Spanish coastline and includes 140 lighthouses. Of these, 91 are rotating, 49 are fixed, and 30 have colored sectors. When you zoom in, you can see the lighthouses in greater detail, including the 3D nighttime relief of the surrounding area.
The map is part of Mapped Earth, which features similar interactive maps for 27 other countries. Each map is built using data from OpenSeaMap and OpenStreetMap, combined with the NGA List of Lights, the official list of navigational aids from the U.S. National Geospatial-Intelligence Agency. This list is a standard reference for nautical charts worldwide.
How the Map Works
Each lighthouse on the map uses the International Association of Marine Aids to Navigation and Lighthouse Authorities (IALA) code to represent its light pattern. The map also projects shadows from the terrain, just as they would appear in reality, adding depth and realism.
The interactive nature of the map allows you to see how each lighthouse flashes or rotates at its real rhythm. This is particularly useful for understanding how mariners use these patterns to navigate. For example, a lighthouse with a group of three flashes every 10 seconds tells a sailor exactly which point of the coast they are passing.

Why It Matters
Lighthouses have been crucial for maritime safety for centuries. Even in the age of GPS, they serve as backup and visual confirmation for sailors. This map celebrates that heritage and provides a new way to appreciate these iconic structures. Context on how this played out before sits in Wuzhen: China's Water Town That Became a Silk Road Hub. A companion piece, Interactive Map Shows All 140 Spanish Lighthouses in Real Time, approaches the same subject from another angle.
Spain's coastline is dotted with lighthouses, each with its own history and characteristics. The map highlights the diversity of these aids to navigation, from the rotating beams of major ports to the fixed lights of smaller harbors. It's a valuable resource for maritime enthusiasts, historians, and anyone interested in cartography.
