Transcriptions of official letters and photographs taken by artist Sebastián Preece (Santago de Chile 1972) while exploringʺ and rescuing the 54 doors of the cells of the CCP Rancagua (abandoned in 2005 and demolished later) to create his metallic and glass installation Puertas: Centro de Cumplimiento Penitenciario de Rancagua (2014). The texts presented here are copies of original letters corresponding to minor causes. Documents I found abandoned in the ruins of the jail before its demolition in the year 2013 and that make up the art project Ex Centro de Cumplimiento Penitenciario de Rancaguaœʺ (HKB Translation, vol. 1). Y PENAS is a compilation of photographs taken in 2013 inside the cells of the abandoned former Centro de Cumplimiento Penitenciario de Rancagua. The surfaces of the walls of the building, as graphic fictions, narrate some of the intimacy and the passage of time in the life of the inmates. This publication complements the book CAUSAS (2014), which gathers transcripts of original trades corresponding to minor causes that were found among the ruins of the aforementioned prison building.ʺ (HKB Translation, vol. 2)
