Dublin , the capital of Ireland is indeed a Viking city. It is so called from Dubh Linn - Black Pool. Baldoyle is an integral part of Viking Dublin, however it has not been proven through physical evidence of Scandinavian presence, but the historical connections of Baldoyle with Viking Dublin are well documented. The name itself Baldoyle or Baile Dubh Ghaill means the town of the dark foreigners. There are many characteristics to describe the Vikings.
Obvious ones mat be cruel, tyrannical, vicious, fiercesome troublemakers, even dictators.
It is true these are fair descriptions due to their actions. But as well as this the Vikings did indeed hold a wealth of qualities as a people and in their way of life. In Dublin alone they have left enough evidence to prove what an advanced race they were. They were a great sea-faring people and perhaps the longships they used are the greatest evidence of the skills they had. Remarkable relics have been found over a thousand years old.
