The viking longship Sea Stallion of Glendalough sails through the Limfjorden in Northern Jutland on August 3, 2008 after its journey across the North Sea. The ship, a reconstruction of a 30 metre long warship built in Dublin in the viking age, is on its way back to the Viking Museum in the town of Roskilde where it built as a reconstruction of the Skuldelev 2-wreck, which was excavated in Roskilde Fjord fifty years ago. Scientific research has established, that the ship was originally built in Dublin by vikings in 1042. AFP PHOTO Henning Bagger/Scanpix 2008 (Photo credit should read HENNING BAGGER/AFP/Getty Images)
