Since the first A Song of Ice and Fire book came out in the '90s, fans have been speculating about the Wall and how it might eventually come down.
With the show nearing its conclusion, the fall of the Wall is looking more and more likely. Especially because there's been some foreshadowing on the show.
As recently as the Season 7 premiere, Sansa dismisses the threat of the Night King due to the safety the Wall affords Westeros.
As some observant Redditors have noticed, the Wall and its surrounds look a little different in the Season 7 credits – almost as though the water near Eastwatch-by-the-Sea is freezing over.
But the idea that the White Walkers and their army could just walk around the Wall is not only incredibly unsatisfying, it also doesn't make a whole lot of sense. (Although it does make their name very appropriate.)
We know it's not just the size of the Wall that keeps the White Walkers out – it's also the magic that the Children of the Forest helped build it with.
It seems the only way the Wall could possibly come down – or become so weak it could allow the White Walkers to pass through/around it – is magic.
The theory goes that Bran passing through the Wall (as we saw him do in the Season 7 premiere) will either cause it to immediately start crumbling (which doesn't seem to be the case at this point), or will weaken its magic so much that it won't be able to stop the dead anymore (which might be more likely).
Then there's the idea – which hasn't really been addressed in the show – that a mythical object known as the Horn of Winter will be able to bring the Wall down.
Then there's another theory which, like the horn, hasn't really been foreshadowed on the show, but is there in the books: that an ice dragon will bring down the Wall.
It won't. The White Walkers will go around it.Bran's mark will do it.The Horn of Winter.An ice dragon.I have another theory (and will explain in the comments).
