Goethe-Institut in Lisbon organized a colloquium about “ephemeral, nomadic, and performance architecture.” Barbas Lopes Arquitectos devised a multipurpose pavilion for that institution based on similar principles. This project, Goethe Salon, was discussed during a lecture about the topics of the colloquium. The presentation made mention to other points of reference, such as the floating theatre of Aldo Rossi and the early happenings of Allan Kaprow. Despite their differences, both relied on the provisional nature of scaffoldings. Simple and straightforward, these props were nevertheless able to define groundbreaking events with great precision. Goethe Salon aspired to the same economy of means, under the guise of a small framework shaped like a pentagon.
