The Escaravox are two 40-meter-span mobile shading devices. They are equipped with sound amplifying systems, stage lighting, and audiovisual projection equipment, so that together with sliding stands, they can accommodate spontaneous public gatherings. They are constructed by assembling inexpensive mass-produced elements, such as irrigation systems, greenhouse fabrics, and plastic chairs.

Located in the public square of Madrid’s former central abattoir—part of the contemporary culture compound Matadero-Madrid—the infrastructures are designed to be available for people to use them, without being invited or curated, through a simple booking process. Different protocols to make them accessible have been experimented with since their opening, gathering an average public of 600 people when active.
