When before, these historical houses symbolized the collective past of a flourishing industry and a strong working class and community, nowadays in some former industrial cities many hundreds of houses in fairly good conditions stand abandoned and boarded-up awaiting demolition. Boarded-up streets and empty houses in general create a unwelcoming and cold atmosphere within the city, they convert neighbourhoods into places nobody wants to inhabit, often affected by crime and vandalism. From an aesthetic point of view, boarded-up windows create a melancholic, mysterious, and sculptural atmosphere. Referring to Gaston Bachelard’s book “The Poetics of Space” windows of houses are described as the souls of houses, when lit up at night, giving us access to their inner life, their history, and memories of past times. The images radiate an uncertainty in relation to their future, producing a sense of instability.
