The Gokstad ship is a 9th-century Viking ship found in a burial mound at Gokstad in Sandar, Sandefjord, Vestfold, Norway. It is currently on display at the Viking Ship Museum in Oslo, Norway.
The site where the boat was found, situated on arable land, had long been named Gokstadhaugen or Kongshaugen (from the Old Norse words konungr meaning king and meaning mound), although the relevance of its name had been discounted as folklore, as other sites in Norway bear similar names. In 1880, sons of the owner of Gokstad farm, having heard of the legends surrounding the site, uncovered the bow of a boat while digging in the still frozen ground. As word of the find got out, Nicolay Nicolaysen, then President of the Society for the Preservation of Ancient Norwegian Monuments, reached the site during February 1880. Having ascertained that the find was indeed that of an ancient artifact, he liaised for the digging to be stopped. Nicolaysen later returned and established that the mound still measured 50 metres by 43 metres, although its height had been diminished down to 5 metres by constant years of ploughing. With his team, he began excavating the mound from the side rather than from the top down, and on the second day of digging found the bow of the ship.
The Gokstad ship is clinker-built and constructed largely of oak. The ship was intended for warfare, trade, transportation of people and cargo. The ship is 23.80 metres (78.1 ft) long and 5.10 m (16.7 ft) wide. It is the largest in the Viking Ship Museum in Oslo. The ship was steered by a quarter rudder fastened to a large block of wood attached to the outside of the hull and supported by an extra stout rib. The block is known as the wart, and is fastened by osiers, knotted on the outside passed through both the rudder and wart to be firmly anchored in the ship.
