Hafnarhús is home to the Erró Collection, and works from the collection are always on display. Erró is one of the pioneers of pop art in Europe, and without doubt one of Iceland’s most well known contemporary artists. In Hafnarhús there is also great emphasis placed on exhibiting progressive and experimental art by renowned Icelandic and international contemporary artists, as well as young, up-and-coming talents.
There are several events held in Hafnarhús each year, and it provides a venue for various festivals, such as Iceland Airwaves. There are six exhibition spaces in the building, in addition to an outdoor yard that is almost unique in Icelandic architecture, a multifunctional space, and a library. There is also a place for children called Moment – A Place to Create, intended for all those who need an outlet for their creativity.
