Lough Tay, also known as the Guinness Lake as it’s owned by the famous family, is one of County Wicklow’s most famous locations, second only to the Glendalough valley.
Vikings fans will recognize it as Kattegat village, home to the series’ hero Ragnar and his family.
Ps. If you view Lough Tay from above (using Google Maps) you’ll notice it loosely resembles a pint of Guinness!
