Hellingly Hospital

With ‘Hell’ right in the title, this place shouldn’t need a ton of explaining. Hellingly Hospital was a 63-acre state-of-the-art insane asylum, but took a sharp turn to Creepytown when the place was abandoned back in 1994. The deterioration of the huge facility has been helped along by arsonists and vandals, though some of them have helpfully brightened up the place with satanic graffiti and threats to eat unlucky explorers.
