You’ve seen the map. The one that plots every known castle on Earth—2,400 dots clustered across Europe, a few scattered in Asia, and a suspicious line along the Ghanaian coast. At first glance, it’s a nostalgic trip through medieval history. But look closer, and you’ll realize something uncomfortable: This map doesn’t show castles. It shows who had the power to define what a castle is.
The Castle Map (thecastlemap.com) is a meticulous project, but it’s built on a deeply subjective classification system. The creator defines a castle as a “fortified structure built for defense and residence”—but that definition is applied inconsistently. Rideau Hall in Canada (a governor general’s residence) counts, but Casa Loma (a Gothic Revival mansion) doesn’t. Why? Because one is officially a “castle” by name, the other is a tourist attraction. The map is a mirror of colonial cataloging, not universal history.
One commenter on the map pointed out: “New Zealand seems to be castle-less—but Larnach Castle exists.” Except it was built in 1871, long after the medieval period. The map’s bias toward European medieval fortifications automatically excludes Larnach, even though it’s called a castle. We’re not mapping history—we’re mapping a 19th-century European fantasy of what history should look like.
Then there’s the Ghanaian coast. Why so many castles there? They’re not medieval fortresses—they’re slave trade forts built by European colonial powers. The map includes them because they’re stone and labeled “castle” in colonial records. But they served a radically different function: not defense of a kingdom, but imprisonment of human beings. Including them without context turns a historical atrocity into a tourist pin on a map.
This is the real problem with the map: it’s a data visualization of Eurocentric bias. Every castle you see is a political statement. The map omits entire traditions of fortified architecture—Japanese shiro, Indian qila, African zimbabwe—because they don’t fit the European definition. We’ve internalized a version of “castle” that only exists in fairy tales and colonial reports.
You might feel a sting of local pride when you see your country’s castles. But that pride is built on a lie. The map doesn’t show what your ancestors built—it shows what European colonizers cataloged. The solution isn’t to add more castles to the map. It’s to question the entire premise: why do we need a map of castles at all? What are we trying to prove?
I’ll leave you with this: Every time you look at a map of the world, ask yourself who made it, and why. The answer is rarely about the world itself. The Castle Map is a beautiful, fascinating artifact of our desire to quantify the past. But it’s also a warning: when we define what counts, we decide what disappears.
FAQ
Q: Isn't the map just a fun project? Why take it so seriously?
A: It is a fun project—but fun projects can carry hidden biases. The map's popularity means it shapes how millions of people think about world history. Ignoring that influence is naive.
Q: What practical difference does it make if a map is Eurocentric?
A: It matters because maps like this reinforce a global hierarchy where European architecture is 'universal' and everything else is 'local.' That affects how we fund preservation, teach history, and even define tourism.
Q: Should we add more castles to the map to fix it?
A: No. Adding more castles just repeats the problem—assuming the European definition is correct. The real fix is to question the definition itself. Call it 'European fortifications' and make a separate map for other traditions.
