The paper is to develop some ideas regarding the relationship between archives and entropy, with a particular focus on the way in which that relationship has played out in art since 1945. The archive is generally treated as an institution founded on order and systematic storage. Yet from the earliest times the degradation of information has been an inextricable part of its operations. On the one hand, this is due to the external threats that affect the archive from outside.

En este trabajo se reflexiona sobre el proyecto Media Sites / Media Monuments del artista Antoni Muntadas en un doble sentido: tomándolo, por un lado, como reflejo del poder de ocultación que ejercen los media sobre determinados acontecimientos históricos y, por otro, como testigo del papel que ejerce la arquitectura, entendida como «anti-monumento», en tanto que depositaria de ciertas informaciones que no han de ser reveladas.
