Reykjavík Art Museum Hafnarhús is a cool spot in Reykjavík that used to be a warehouse by the harbor but got a makeover in 2000. Now it's a hip art space with six galleries, a courtyard, and even a multi-purpose room for all kinds of events like rock concerts and poetry readings. You can check out works from the awesome Erró collection, donated by the Icelandic pop-artist himself. It's a must-visit for art lovers and anyone looking for a unique cultural experience in Iceland's capital city.
