After the death of Franco, public attention shifted to the Nationalist repression. Memory of victims of Republican violence in Madrid was cultivated mostly by their relatives, but it periodically gained renewed attention, especially in relation to Santiago Carillo; his re-entry into politics sparked a heated controversy, which continued for decades and climaxed in a failed attempt to launch legal action on basis of presumed crimes against humanity. Some major new publications, e.g. the 1983 Ian Gibson's work on Paracuellos, renewed public attention; it was also the case of beatifications, proceeded and completed by pope John Paul II in the 1990s and Benedict XVI in the early 21st century. Public debate on role and official acknowledgement of the Madrid repression system continued. In 2015, the Comisionado de Memoria Histórica marked the Bellas Artes checa, the Modelo prison and the Porlier prison to feature among 15 "sites of historical memory" in Madrid. The proposal generated ongoing public controversy related to the list of sites and exact wording used. Initially, it was intended to mount plaques commemorating the victims, but according to legal expertise obtained the proposal would be incompatible with Ley de Memoria Histórica, which prohibits "exaltación de la sublevación militar, de la Guerra Civil y de la represión de la Dictadura". So far, minor plaques are currently mounted in premises which do not form public space like in religious buildings. Debates related to other initiatives of the Madrid town hall continue.
