Warfare and warrior identity were central to the Viking way of life, contact with other cultures was violent, and looting was commonplace – Vikings were both raiders and traders. The Viking expansion from Scandinavia created an extensive cultural network – from the Mediterranean to the Arctic Circle, and these many influences are reflected in this major collection of discoveries including weapons and looted treasures and jewellery. The surviving timbers of a 37-metre-long Viking warship is the centrepiece of the exhibition, the longest ever found. Fascinating.
