Every year since 2008, Italian fashion house Zegna have commissioned an artist to create and install a permanent site-specific artwork near its headquarters and textile mill in the Trivero area of northern Italy.

Called All'aperto, the programme is curated by Ermenegildo Zegna's grandson, the architect Andrea Zegna, alongside journalist and art critic Barbara Casavecchia who together, over the years, have secured contributions from artists Daniel Buren, Alberto Garutti, Stefano Arienti, Roman Signer, Marcello Maloberti and Dan Graham.

This year, linking all of the programme's previous works together, Milanese artist Liliana Moro has created a number of interventions that serve as a guide for tourists. Called '29,88 sq km', Moro's installations are spread across two locations, continuing the programme's tradition of function over frippery.

The first is a brand new pentagonal information point that greets visitors at the Piazza della Repubblica roundabout, where a series of digital displays detail initiatives promoted by the City Council, the weather conditions and the events scheduled in the Oasi Zegna nature park. A series of large images of animals commonly found in the surrounding woods and mountains are emblazoned across the pavilion's glass walls.

Just a few hundred metres away at the Centro Zegna tourist information office, Moro worked with a cartographer to create an interactive three-dimensional map of the '29,88 sq km' area – the figure that prompted the exhibition's title. A series of small lights identify each location of all the All'aperto artworks to date, while the voice of Moro – mimicking the old coin-operated audio guides found in many historical art sites in Italy – describes them in her own words, to bring 'a fresh look to the projects'. 

Together with musician Tommaso Previdi, Moro has also developed a characteristic sound for each of the guides – sound being a favoured medium for Moro, who in the past has created installations and sculptures using megaphones, loudspeakers and tape recorders.
