The Sun Voyager is a massive steel sculpture by Jón Gunnar Árnason that many people assume is a Viking ship, however it was designed as a dream boat and ode to the sun. The sculpture is located along the seafront close to the center of Reykjavík, with view of Mount Esja over the water to the north. The Sun Voyager won a competition for an outdoor sculpture to commemorate the 200th anniversary of Reykjavík in 1986, and was unveiled in August 1990. The artist had been ill with leukemia during the construction of the full-scale sculpture, and died in April 1989. For more back story, the Wikipedia article has more information about the concept and location of the Sun Voyager.
Although there’s a fairly busy divided boulevard running along the seafront, the sculpture location is rather peaceful. It’s on a bit of a peninsula, and it’s easy to focus on the sea and mountains in the distance and forget the city is right behind you. It was overcast and a bit drizzly when I visited, so the sculpture was a bit muted, so I could really appreciate the shapes and the interaction with the site. It certainly has ship-like qualities, and also a bit of bug/crustacean-ness, which some might find off-putting but I found endearing. It somehow kept it accessible, although I didn’t feel comfortable enough to climb on it, which some other people who were there while I was did.
