In 2007, New York-based artist Roni Horn -- who has traveled widely in Iceland for more than 30 years -- unveiled this permanent architectural installation inside a former library on a hill overlooking Breiðafjörður. The space has 24 floor-to-ceiling transparent columns, each filled with water from a different Icelandic glacier or glacial river. English and Icelandic adjectives associated with weather are inscribed on the vulcanized rubber floor. With Iceland's glaciers rapidly shrinking, Vatnasafn has an implicit environmental message but is hardly a polemic. Vatnasafn is also a community center for local reading groups and chess players; check the website for concerts, film screenings, or other events.
