The exterior looks like it once was a gracious building, but what the heck happened here one wonders!
Seems like someone has plans to restore it, no wonder you two were scolded like 2 little schoolboys :)
I'm a real sentimentalist as buildings like this always put my imagination into overdrive - there once was life in there, likely originally a family home turned into a nursing home, and now just a smelly mess!
I still say you are brave for venturing into these derelict buildings.
Here in SA we're starting to see abandoned homes here and there, but the difference is they get stripped of EVERYTHING by thieves; plumbing, electrics, steel gates, doors, window frames, whatever they can take, till only the brick shell is left; it's just awful!
But, you have fun, just don't get caught next time :):)
