Zodiac Machine is an exhibition by Justin Caguiat, presented by Fundación Sandretto Re Rebaudengo Madrid, curated by Hans Ulrich Obrist and produced by Isabela Mora. The exhibition will unfold in two parts, beginning in Madrid from March 4 through April 1, 2026, and continuing at the Serpentine Gallery in London in autumn 2026.

The exhibition consists of a site-specific installation across the Santa Ana y la Esperanza Church, Moratalaz Market, and surrounding public spaces. Caguiat’s works spill across public spaces, squares, shopfront windows and walls, and into the Moratalaz market - a two-storey building where the ground floor hosts various food stalls and local businesses. Several unused units are occupied by the contents of the exhibition.

The church, designed by celebrated Spanish architect Miguel Fisac (1913-2006), was constructed between 1965 and 1971 during a period of liturgical and architectural reforms following the Second Vatican Council. The encouragement of ‘full, conscious and active participation' led to architecture aligned with Modernist principles of pure and simplified form: horizontalization was favoured over verticality; the altar became the focal point; radial forms privileged the congregation. The church’s cavernous nave was designed with three convex curves to democratise acoustics across the whole room, and geometric courtyards and classrooms were constructed to flank the chapel.

An important early inspiration for the conception of Zodiac Machine was the Catedral de Justo, a large religious structure in Mejorada del Campo, built single-handedly by Justo Gallego Martínez between 1960 and 2021. After contracting tuberculosis, Gallego vowed to dedicate his life to building the cathedral if he recovered, as a shrine to "Our Lady of the Pillar," with a complete vision of its geometry, morphology, and construction from the moment of its conception. Justo, with no formal architectural or technical training, built the entire structure using recycled and found materials.

Caguiat’s artworks installed across Moratalaz - consisting of painting, sculpture, printmaking, photography, film, and sound - were developed as a single, unified vision made expressly with Justo's philosophy in mind. They respond to Justo’s unfettered creative freedom as a liability rather than an ideal. Zodiac Machine draws from the wayward architect’s total devotion, producing forms that are both generative and untenable.
