Exactly What It Says on the Tin
: Suppose the Big Bad
has a very definite territory he calls his own, from where his hordes of darkness spawn. It's good because you always know where the baddies come from, but what do you do if you don't have the necessary manpower to end them once and for all?
Simply: just put a wall between you and them. The bigger, the better.
The Great Wall is what happens when you try to get your enemies not only out of your city but of your county, state or country, resorting to the simple mechanism of building a wall that will (one hopes) keep them out.
It's similar to The Wall Around the World
, except that this is more about separating two realms from each other, whereas The Wall Around the World
is about separating one realm from everything else. The most famous Real Life
example is, of course, The Great Wall of China
, which may have been the inspiration for many fictional Great Walls, although the Berlin Wall and Hadrian's Wall have also been influential.
May be an Absurdly Ineffective Barricade
if it doesn't work. Compare Insurmountable Waisthigh Fence
. Invisible Wall
works like that.

Anime & Manga
- Attack on Titan has the last known human city hiding behind three nested circular walls. Both the fact that it works as a prison and that it won't keep out the titans forever are acknowledged by the story, although various characters are in denial of both. The outermost wall is breached in the first chapter.
- The Gate Wall in Darker than Black used to ward off the negative effects of the Hell's Gate.
- In Infinite Crisis, the Green Lantern Corps erect a 7-mile thick wall to hold back Super-boy Prime. It fails.
- One of the main features of Skull Island is a wall built by the human inhabitants to keep Kong and the dinosaurs out of their village. Pity they included such a huge gate...
- In Pacific Rim, mankind begins building walls as a last-ditch effort to keep the Kaiju out. It's clear from the outset that it won't work.
- In The Last Starfighter, the Star League created The Frontier, a force field barrier generated by a pattern of fixed devices. It was designed to keep out the Ko-Dan Armada, the starfleet of the Ko-Dan Empire.
- In A Song of Ice and Fire, Westeros has a massive (as in 800 foot-high) wall built of ice blocks in the far north, stretching from the continent's east coast to the west. The Wall was built to keep out the Others, "demons made of ice", and is manned by the Night's Watch. The Wall is so old that most people have forgotten all about the stuff that lives behind it, but they're unpleasantly reminded when the Wildlings attack, followed by the Others.
- In Codex Alera, a giant wall protects the Realm from the Icemen. By the end of the series, it protects the Icemen from the Realm. Same end result, but a different perspective from the people involved.
- The one located in the town of Wall in Neil Gaiman's Stardust.
- There's one of these in Garth Nix's Old Kingdom books, separating the nonmagical land of Ancelstierre from the Old Kingdom, where there's necromancy and other magic. It's actually an artefact containing one of the five Cosmic Keystones that keeps the Charter together and is designed to keep anything nasty inside the Old Kingdom where people know how to deal with it. It's only moderately successful, hence the massive trench and bunker network on the Ancelstierran side.
- Chattergy's Wall from Haroun and the Sea Of Stories separates the perpetual daylight of Gup from the benighted land of Chup.
- In Rudyard Kipling's Puck of Pook's Hill, Centurion Parnesius is Reassigned to Antarctica on Hadrian's Wall.
- Hadrian's Wall and the Antonine Wall loom large in Rosemary Sutcliff's stories of Roman Britain, notably The Eagle of the Ninth, The Mark of the Horse Lord, Frontier Wolf, and The Capricorn Bracelet, whose protagonists either have to build them, garrison them, cross them, or get Chased by Angry Natives back to them.
- Legend of the Five Rings has the Kaiu Wall between the Shadowlands and Rokugan, where the Crab Clan spend their lives protecting the rest of the Empire from the demonic forces. It is a point of both pride and annoyance for the Crabs that no other clan knows of how hard their duty is.
- World of Warcraft has The Serpent's Spine, a very exact copy of The Great Wall of China cutting a large western sector off the rest of Pandaria - erected by the Mogu emperors to keep out the periodic Mantid swarms.
- Guild Wars had a Great Wall in Ascalon, which kept the charr in the northern lands. Its penetration is what started the initial game's plot. Many parts of it still stand come the sequel.
- In Grandia, there's a gargantuan mile-high wall that bifurcates an entire continent.

- In Ancient China, The Great Wall divided the kingdom from the Mongol horde. When it was built, there was no Horde nor any development to this end yet, only mentions of prices on slaves dropping. And once there was the Horde, the wall didn't slow it down much. Not that one overstretched and undermanned fortification line could be reasonably expected to do this anyway.
- The Berlin Wall, which both literally subdivided the city of Berlin, and became a symbol of the proverbial Iron Curtain dividing the communist and capitalist worlds.
- Hadrian's Wall and the other limes walls of Ancient Rome, built for keeping Celtic and Germanic tribes at bay.

- In Australia, the Dingo fence protects southeast Australia from dingos.
- The Maginot Line, built by the French in the 1930s to defend against a German invasion. Unfortunately it only covered part of the border, allowing the Germans to invade through the uncovered part. The money the French spent on it limited the amount they could spend on their armed forces, contributing to their defeat in World War II.
- The Great Wall of Gorgan protected the various Persian empires from invaders from the north by closing the gap between the mountains and the Caspian Sea, and was the second-longest defensive wall in recorder history after the Great Wall of China. Made doubly impressive by being built entirely of brick.
