Construir universos is a workshop led by the young artist Ignacio Chávarri. In it the participants reinterpret the exhibition by the German artist, Rosemarie Trockel: a cosmos. The experiences they have in the rooms activate the creative process: the children take as their point of departure both the contents of the Museum and the items they find in their personal space (bedroom, drawers, backpack…) and they put them together in a private cosmos that contrasts with the collective cosmos that they create all together.
