Guglielmo Castelli

Guglielmo Castelli was born in 1987 in Turin, Italy, where he still lives and works. He trained in set design and theatrical scenography at the Accademia Albertina di Belle Arti in Turin, a background frequently cited by galleries and critics as shaping the staged, dreamlike quality of his paintings.

Early recognition came through Italian regional prizes, including a special award for painting at the Combat Prize in 2015. His first significant institutional solo show followed in 2018 with Goodmorning Bambino at Kunstlerhaus Bethanien in Berlin; his work has also been shown in a group presentation at the Fondation Louis Vuitton in Paris. In 2019 he won the Premio Ettore e Ines Fico at Artissima and the Premio Casarini Due Torri at ArtVerona.

His profile widened through 2020, when he was included in the 17th Quadriennale d'arte di Roma at the Palazzo delle Esposizioni. Gallery representation with Mendes Wood DM followed, with solo exhibitions in Brussels in 2021 and New York in 2023, alongside representation by Sylvia Kouvali. Museum recognition accelerated further with a 2024 solo exhibition at Fondazione Bevilacqua La Masa in Venice, a solo presentation at Villa Medici in Rome the same year, and a three-artist exhibition at Castello di Rivoli Museo d'Arte Contemporanea in 2025. In February 2026, Kunsthalle Wien opened Sweet Baby Motel, described by the institution as his first solo exhibition outside Italy.

Institutional attention has arrived quickly and consistently. Castelli was named to Forbes' 30 Under 30 list for European visual arts in 2016, and by the mid-2020s his work had been shown at the Fondation Louis Vuitton, the Quadriennale di Roma, Castello di Rivoli, Villa Medici, and Kunsthalle Wien. Writers and curators discussing his work consistently return to his training in theatrical scenography, reading his paintings as staged, dreamlike scenes populated by faded or spectral figures, a vocabulary that institutions have treated as a distinct and coherent voice within contemporary figurative painting rather than a passing trend. No single named critical assessment could be verified to the exact wording needed for direct quotation, so this profile summarizes the recurring themes of that coverage rather than quoting it.

Castelli's auction record is Drunken Incantations, a 2020 oil on canvas that sold at Sotheby's London in March 2023 for USD 244,546 (a GBP-equivalent figure is not confirmed in available reporting). The exact day of sale is not specified in available reporting; the month and year, March 2023, are as reported by the Observer in 2025. His secondary market otherwise remains young and thin: Bite the Bullet (2021) realized GBP 151,200 at Christie's London in October 2024 against a much lower estimate, but most public results for his work, at Sotheby's, Christie's, and Phillips, have been considerably smaller. No external best-selling-artist ranking has been confirmed for Castelli specifically; his market is best read as an emerging one with a handful of notable single-lot results rather than a long, deep sales history.

Castelli's market is defined by rapid institutional validation running ahead of a still-developing auction history. His single confirmed high result, Drunken Incantations at Sotheby's London in 2023, sits well above the bulk of his other public sales, so collectors should treat any one auction result as an early data point rather than a stable benchmark. There is no catalogue raisonne, and authentication in practice runs through his two representing galleries, Mendes Wood DM and Sylvia Kouvali, which makes clean provenance and gallery documentation especially important for any work considered for acquisition.
