It is a mobile architectural structure built with scaffold-jointed tubing and covered in spinnaker fabric of various colors. The air inside changes in relation to what it hosts, and it can be relocated elsewhere.

Inside it, the exhibition Qui la liquidilà is presented, which will move to the gallery from March 30 to April 18, 1992.

The exhibition tells and makes visible the ways in which the three artists sought to establish a relationship with the women inmates of the Female Section of the San Vittore Prison.
