Vatnasafn/Library of water is Artangel’s latest and first international commission. Working with artist Roni Horn, Library of water is located in the small Icelandic town of Stykkishólmur. During visits to Stykkishólmur, hearing that there were plans to move books from the library building – perched on top of a hill, overlooking the harbour and ocean – Horn, who described the building as the most beautifully situated library in the world, put forward initial ideas for new uses for the library building.
