The performance of large stadium projectors inspired Cestello, an innovative lighting system for cultural spaces. On show until January 2025 at the Triennale Milano

The companies that have made design history are distinguished by the continuum of collaborations with great masters of architecture and design capable of transmitting a futuristic vision to entrepreneurs with their culture and creativity. iGuzzini is among the companies that have always elaborated on these collaborations with their DNA, investing in research, development and innovation and achieving solutions never before explored in the lighting sector.

A piece that has made history

Cestello represents the emblem of iGuzzini's history which, more than 30 years after its production, still illuminates some of Gae Aulenti's most important architectural projects: the cross-section of Palazzo Grassi in Venice and that of Perugia Airport reproduced on a 1:1 scale, part of the exhibition that Triennale Milano dedicates to her, realised in collaboration with the Gae Aulenti Archive and curated by Giovanni Agosti, Nina Artioli and Nina Bassoli.

Unexplored lighting solutionsi

Guzzini's meeting with Gae Aulenti took place on the occasion of the project to transform Palazzo Grassi in Venice into an exhibition gallery for temporary exhibitions, entrusted to her in 1983. Aulenti and Piero Castiglioni came up with lighting solutions that could not be achieved with existing products at the time.

A projector of new conception

For the spaces of Palazzo Grassi, they tackled the design of a projector of a new conception, suitable for illuminating particular spaces and which finds its inspiration in the projectors installed in stadiums to be rethought for interior design projects: thus Cestello was born, a compact group of projectors that can be individually oriented, without the need for tracks, and which creates direct illumination amplified by reciprocal reflections.

From craftsmanship to seriality

Cestello was initially made in an almost artisanal way to illuminate Palazzo Grassi, but then began a path of engineering and industrialisation tackled by iGuzzini together with Aulenti, Castiglioni and Fiat (then owner of Palazzo Grassi) to make Cestello a serial product in 1993, sold in large numbers and expanded over the years. Cestello has illuminated some of the world's most famous architecture: Palazzo Ducale in Venice, Scuderie del Quirinale in Rome, Le Samaritaine in Paris, Galleria Borghese in Rome.

The exhibition at the Milan Triennale

For the exhibition ‘Gae Aulenti (1927-2012)’ at the Triennale di Milano (until January 2025), iGuzzini is also a technical partner. The section ‘Arrivo al Mare’ is illuminated with iSign luminaires installed on the ceiling. For the reproduction of the Olivetti showroom in Buenos Aires in 1968, Reflex recessed luminaires. For the section recreating Christo's exhibition at the Rotonda della Besana in 1973, Underscore 15 backlights the ceiling. For the Musée d'Orsay, the installation exploits the Palco projectors already existing in the Triennale spaces. Finally, the Spazio Oberdan is illuminated with Frame.
