Recently, I have been going back to re-visit an abandoned school I first photographed in 2010. The vandalism, tagging and scrapping since then has exploded! Fully open to the elements (IE, extremes of wet and humidity and bitter cold) have turned the paint and the floor and ceiling tiles into brittle chips.
Not the same room, but close. The general layout of all the rooms were more or less the same. I really like the little bookcases in the corners. First photo from 2010:
