The thing that makes this an important discovery is the fact that it is on the mainland. There have been Viking ship burials found in the Orkneys but never one on the NW coast of the mainland.
Will be interesting to follow this through and see what the finds tell us. There are of course other ship burials that have been found in the UK probably the most famous of these was the discovery at Sutton Hoo which is a fascinating day out and well worth a visit.
