The 'Anti-Zombie Fortress' meme first gained traction on 4chan and Reddit in the late 2000s, typically featuring a photograph of the vertical, spiral-shaped Nakagin Capsule Tower or unique architectural structures like the abandoned Haizhu Bridge in China. Users would present these buildings as the ideal sanctuary during a hypothetical zombie outbreak, sparking viral debates over supply chains, accessibility, and structural integrity. Today, the template is used to showcase any absurdly secure or isolated location, often reflecting a humorous desire to escape social interactions or global chaos as much as the undead.
