In the city of Madrid it is common for the streets to be under repair and old cobblestones are being changed in many places to keep the sidewalks in good condition.

The work consists of extracting one of these from a cluster of new paving stones so that it cannot be installed on the pavement.

The action is based on the understanding that the sidewalk, the cobblestone, is the sustaining base of everything, where all the political-social plots unfold, that is, it is the base that literally sustains a society. By extracting this sidewalk, it can never be placed at the base of the city and thus it will never be part of the support of the reigning monarchy in Spain.
