Aspectos de la desaparición. Calles y subterráneos

This essay discusses issues related to disappearances in urban space, in par- ticular cases that affect streets and subways, the mismatched equivalences of lines on the surface of urban space and what lays underground. Taking as a point of departure David Pike’s concept of threshold, which is key to defining a topography of the “vertical city”, a reading of plans and literary texts and films is proposed. This will illustrate the ways in which surface and other underground spaces overlap and the many differences that exist.
