A Viking invasion will take place on Sunday the 20th of August thanks to the Irish National Sailing School in Dun Laoghaire, County Dublin.
The centre piece of the event will be a re-enacted battle between two of the longboats and their 30 crew at 3pm. The Viking's are expected to sail/row from the mouth of the harbour towards the bandstand, where the crews will do battle on the water before coming up onto the pier and battling a further 30 Vikings in a Viking village on the East Pier.
It's perhaps not that well known but another string to the INSS bow is the company's work in the film industry as marine experts. Specifically, INSS's Alistair Rumball has been involved most recently in the hit TV series Vikings that is produced in County Wicklow.
So this Sunday is a great opportunity to witness what goes on behind the scenes on one of the film sets for the series.
