The Irish have cold feelings towards the memory of the Vikings. But, aside from their horrible raids and murders, the Vikings did do some good for the Irish. For example, one of Dublin’s most visited churches, the Christ Church Cathedral was built by the order of Norse King Silkbeard around year 1030. Additionally, some of the settlements the Vikings created still stand today such as Waterford, Cork and Dublin. Some of the most prevalent Irish names also came from the Vikings. Doyle (son of the dark foreigner) and MacManus (son of Manus) both stem from Scandinavian warriors. So, maybe the next time the Vikings come up in conversation, give them a little credit.
