The Centre for Contemporary Art and Sustainability (CACiS) El Forn de la Calç has a permanent collection of works by different artists who have had a residence at CACiS, who have participated in projects or who have simply made a donation to the Centre.

Some of these works, especially those installed in the open air and due to the plant materials that they are made of, are ephemeral and, with the passing of time and the effect of the weather, have disappeared or will soon do so. However, they live on in the documentation archive.
