The Murs Oberts system makes available to citizens a set of specifically located and signposted spaces in which free artistic expression is permitted through any of the techniques and languages of urban art, without the need to request prior permission.

The only requirement to intervene in an Open Wall is to respect the basic code of operation and coexistence in the use of the spaces.

The Murs Oberts system does not provide for any specific conservation or maintenance of the creations that are generated since they are spaces that can continuously welcome new proposals.
