Surreal mud-purple landscapes are inter­mingled with visions of trolls, giants and dead men walking at the National Gallery of Iceland. Iceland’s main art gallery, overlooking Tjörnin, certainly gives an interesting glimpse into the nation’s psyche. As well as a huge collection of 19th- and 20th-century paintings by Iceland’s favourite sons and daughters (including Ásgrímur Jónsson, Jóhannes Kjarval and Nína Sæmundsson), there are works by Picasso and Munch.
