Complete isolation within your padded cell walls. The screams and unintelligible ramblings of your fellow inmates. The torturous “treatments” that are more terrifying than the monsters in your own mind. What could make a better setting for horror than the madhouse? As popular as lunatic asylums still are in modern horror, this setting has its roots deep in Gothic literature—going back further than you might think. Indeed, like so many of the other recurring Gothic settings, these institutions lend themselves particularly well to Gothic tropes. Isolation and imprisonment are at the core of the asylum’s function. Any story set within its walls can use the spectacle of insanity as the engine of horror. And apart from madness itself, there are also the horrors of the cruel treatment, cramped spaces, and poor physical conditions that unfortunately characterize such institutions.
