Wanted to find our more about the water in Iceland so I googled it, and realised they have a Library of Water in Stykkishólmur, with an installation by an artist called Roni Horn. The installation was made up of water collected from Icelandic glaciers! Apart from that the artist did quite a lot of work related to water and nature, while her works are very poetic and minimal.
