We were asked by Solid Nature/OMA to design a tribune, a spot in the garden of Spazio Cernaia for conversations and presentations. We interpreted the tribune as a ‘piccolo teatro’, a mineral theatre for small and big talks during the Salone. Being in a garden, we thought it would become a small observatory where to look at guests, but also at birds and other creatures of the garden: along with sitting space for people are three pigeon towers reserved for very posh Milanese birds who might attend the events. At the center, a gravel-filled courtyard is a place for performances, lectures, dances, or a mineral canvas where to just draw ephemeral bas reliefs during a break. We thought of a variation on Elizabethan theatres, with the scene at the center and the public around it: we imagined that anyone could step onto the stage and, in an instant, shift from audience to actor, speaker, or performer. We also looked at the playgrounds and gardens of Isamu Noguchi, the Teatro del Mondo by Aldo Rossi, the Mughal astronomical observatories, to marble quarries in Iran and Italy.
