About this place
Ferro Meridian, near Frontera on the Canary Island of El Hierro, marks a historical reference line for measuring longitude.
What exactly is the Ferro Meridian?
It is a geographic reference line running along the western edge of El Hierro, the smallest and westernmost of the main Canary Islands. Before the world settled on a single shared coordinate system, different countries measured longitude from their own "zero point." Spain — and with it many European maps and atlases — used El Hierro as that zero meridian for a long stretch of history, long before Greenwich became the global standard it is today.
Why was this particular island chosen?
El Hierro sat at the very edge of the known world at the time — the westernmost scrap of the Old World before the Atlantic opened onto the New World. That position had a practical advantage: it let cartographers count longitude in one direction only, without negative values, which simplified navigation and map-making during the age of exploration. As sea navigation and cartography later demanded one universal system, the world shifted to the Greenwich meridian, leaving Ferro as a historical curiosity and a local point of pride.
Where exactly is this location?
The coordinates commonly associated with the Ferro Meridian sit around 27.71°N, 18.15°W, placing it within the municipality of Frontera on the western side of El Hierro. This isn't a monument or building in the usual tourist sense — it's a geographic and historical reference point that, for centuries, appeared on European maps as longitude "0°."
What should visitors know before going?
El Hierro is an island of quiet, raw volcanic scenery, far removed from the crowds found on Tenerife or Gran Canaria. Visitors who seek out the Ferro Meridian usually aren't chasing a dramatic view — they're drawn by the idea of standing at a point that once anchored maps across Europe. It's a good excuse to pair a short stop here with time spent exploring Frontera and the island's western coast, an area known for its volcanic landscapes and the calm, unhurried character that sets El Hierro apart from the rest of the Canaries.
Frequently Asked Questions
How is the Ferro Meridian different from the Greenwich Meridian? Both are conventional zero-longitude reference lines, but they mark different points on Earth. Greenwich, in London, is the current international standard, while Ferro was an earlier reference line used mainly by Spain and some European maps before the world agreed on one global system.
Is there a monument or marker at the Ferro Meridian? The Ferro Meridian is primarily a geographic and historical concept tied to the western edge of El Hierro in the municipality of Frontera, rather than a single dedicated tourist structure.
Why was El Hierro chosen as the zero point? The island lay at the far western edge of the world as known at the time, which allowed longitude to be counted without negative values — a practical choice for the maps and navigation methods of that era.
Is it worth visiting if I'm not interested in cartography? Yes — it's a solid reason to explore the quiet, volcanic landscapes of Frontera and western El Hierro, one of the least crowded islands in the Canaries.
