Reykjavík Art Museum
Also known as Hafnarhús, this former warehouse of the Port of Reykjavík now houses the city's main art museum. The six galleries occupy two floors, and there's a courtyard and "multipurpose" space. The museum's permanent collection includes a large number of works donated by the contemporary Icelandic artist Erró. There are also regular temporary exhibitions. Admission is free with the Reykjavík City Card.
