Been thinking about this for a while and honestly yes, completely agree. Old hospitals have that combination of mass trauma, repetitive routine, and sheer volume of deaths over decades that cemeteries just can't match. A cemetery is where bodies end up, but the actual distress happened somewhere else entirely.
The old Victorian workhouse infirmaries are particularly interesting to me. Places where people died largely forgotten, sometimes in quite horrible circumstances, with no family present. That kind of ending seems to leave a stronger imprint than a natural death at home surrounded by loved ones. Purely my own theory but it fits with a lot of what I've read and experienced.
I did a vigil at a decommissioned NHS hospital in West Yorkshire about four years back and the activity in the old surgical wing was more consistent than anything I've encountered in a graveyard. Not necessarily dramatic stuff, just persistent. Footsteps, temperature drops in specific corridors, the feeling of being watched from doorways.
Anyone else noticed that hospitals from the late 1800s seem notably more active than mid 20th century ones? Wondering if building materials play any role in that.
