The city of Tortosa is going to welcome A Cel Obert again in 2021!

A Cel Obert chooses a theme for each of its editions with the aim of creating a common thread that generates conceptual relationships and works as a link between the different ephemeral interventions. For this reason, the jury will assess, among other aspects, the adequacy of the participants vis-à-vis the proposed theme as well as the originality and quality of their interpretation of the concept whether understood in a literal or metaphorical way.

The festival also coincides with the celebration of the European Heritage Days (EHD), where towns and organisations all over Catalonia join in a major celebration of our cultural heritage. That is why we have planned free activities for these days, to bring the richness and diversity of our cultural heritage closer to the public.


With 2022 marking the centenary of the death of the Tortosa-born musician and composer, Felip Pedrell, the theme of the ninth edition of the A Cel Obert festival is Rhythm.
The spectrum that the concept of rhythm encompasses is as concrete in its meaning as it is plural in its aspects: rhythm of life, circadian rhythm, biological rhythm, respiratory rhythm, or sinus rhythm. But also musical rhythm and compositional rhythm. In addition, rhythm of reading, poetic rhythm, visual rhythm, rhythm of light or natural rhythm.

Human evolution has been linked, probably intuitively and unconsciously, to understanding what it is and how the rhythm of things works. Rhythm is an internal structure that temporarily defines everything that happens and everything that happens to us: it is who regulates the content of things and also the continent of them. Without rhythm, there would be no order and nothing could be organised. Chaos would reign continuously, and nothing would be possible except for those moments where chance and coincidence will it.

Once again, A Cel Obert will have a first-class panel of judges made up of well-known professionals from the world of architecture, plastic arts and design. Based on the theme chosen for this edition, Rhythm, the judges will assess, among other relevant aspects, the participants’ adaptation to the proposed theme and their originality and quality in capturing the concept in their ephemeral interventions, whether this is understood literally or metaphorically.
