That place looks to be incredibly sturdily built! The corner where it's been partially demolished (in the second-to-last photo) makes it look like the facade was rough-hewn stone OVER brickwork. That's a lotta sturdy stuff to bust through. But modern demolition techniques will prevail.
I was 100% with you in believing that the building had been some sort of detention center though. That wallpaper alone was enough to punish anyone spending time there! 😵
Thank you for sharing!
