4. Arkham Asylum for the Criminally Insane
Ah, Arkham Asylum. A serious house on serious Earth. Gothams resident nut-house has featured heavily throughout Batman lore since the late seventies. Originally it was featured as Arkham Hospital. It was only later that it was fully established as a Sanitarium and only throughout the eighties that it was properly established as
the place for around 70% of Batmans detainees. Since then, Arkham Asylum has become perhaps one of the most iconic locations in the entire Batman canon and has been featured heavily across every media platform the Dark Knight has enjoyed a presence on over the years, including in Nolans own trilogy. If you dont know Arkham Asylum, you clearly
dont know your Batman lore, its as simple as. But since its now even famous in the mainstream (you can thank the awesome Rocksteady Arkham games for
that), chances are that even if youve never picked up a comic book in your life youll still have a fair amount of knowledge on the place.
