The Scandinavians first appeared in Scotland at the end of the eighth century. An artefact depicting this early contact is the "Hostage Stone" found on Inchmarnock, a small island off the coast of Bute. In 2014 this small stone travelled to Denmark, a journey that would surely have amazed its inscriber!
Stimulated by this story, I visited the Viking Ship Museum in March 2015. The Hostage Stone was returned to Bute in December 2014 at the end of the Special Exhibition, but this excellent Museum is well worth a visit at any time, as also is Roskilde Cathedral and the Danish National Museum in Copenhagen.
