Viking World is a museum in Njarðvík, about 4 km from central Keflavik, dedicated to the Norse settlement of Iceland and the broader Viking Age. The highlight is Íslendingur, a full-scale replica of the Gokstad ship that actually crossed the Atlantic in 2000. Seeing it at close quarters — the overlapping clinker planks, the dragon prow, the shallow draft — makes the Atlantic voyages of the Norse settlers feel more real and more audacious than any written account.
The museum also covers the voyages of Leif Eriksson to North America and reconstructs aspects of Viking-age life in Iceland. It is aimed at a general audience and is accessible without specialist knowledge. Allow 90 minutes to see it properly.
