The story
When Trans-Allegheny opened in 1864, it was a model of humane treatment - spacious rooms, natural light, therapeutic work. But as mental health funding dried up, the population exploded. By the 1950s, a building designed for 250 held nearly 2,400 patients in squalid conditions.
Lobotomies were performed regularly. Patients were chained to walls. The "criminally insane" unit, Ward F, became particularly notorious. When the asylum finally closed in 1994, it was one of the last to still use restraints and seclusion.
The building itself is staggering - the second-largest hand-cut stone masonry building in the world, after the Kremlin. Its 242,000 square feet contain countless stories of suffering, experimental treatments, and deaths that were never properly investigated.
