This is a site-specific installation. A monitor showing the video was installed in the locked out backstairs of an apartment building, dating back to the first years of the 20th century and presently uninhabited, located at Avenida da Liberdade, in Lisbon. The video is only visible through the peephole of a locked-up door in the kitchen of one of the flats. That special door in that kitchen gives access to the backstairs of the building that were originally intended for the exclusive use of servants and suppliers. The specialized use of the front- and the backstairs corresponds to functional and class segregation that was thought natural in those days, a reflection of a social organization that fostered visual separation between the menial activities and the world of the masters, the private and the public. The images were filmed in situ and show the perspective of someone going up and down the backstairs, trying unsuccessfully a key in every locked door he comes upon. Because of the place where the video is installed (a monitor placed in the locked up backstairs), it works as a metaphor of multiple readings.
