Unspoken Spaces is the first major book on Olafur Eliasson’s architectural projects and works in public spaces around the globe. The book explores, often in Eliasson’s own words, the artist’s driving interest in finding visionary shapes to represent abstract ideas, and presents an extraordinary visual journey through spheres, tunnels, towers, walkways and archways, as well as pavilions and larger buildings realized by Eliasson and his studio since the late 1990s. Eight essays by writers across a variety of fields—from geologists and historians of art and science to architects, artists and philosophers—give further insight into the work of Olafur Eliasson.

Works in Unspoken Spaces range from small-scale experiments to largescale projects in the public realm, among them striking buildings such as the Serpentine Gallery Pavilion 2007 in London (with Kjetil Thorsen), Your rainbow panorama (2006–2011) in Aarhus, Denmark, the crystalline façades for Harpa Concert Hall and Conference Centre in Reykjavik (2005–11), and Cirkelbroen (The circle bridge) in Copenhagen, Denmark, 2015. Each work is presented with vivid photographs and accessible in-depth project descriptions as well as Eliasson’s more personal statements.

Unspoken Spaces includes a range of Eliasson’s creations—“reality machines,” as he calls them—many of which have never appeared in print. A section of the book explores unrealized and unfinished projects.

The contributing writers are Alex Coles, Lorraine Daston, Carol Diehl, Eric Ellingsen, Timothy Morton, Molly Nesbit & Minik Rosing.
