When was linen making established in Northern Ireland?

Answer 1

An exact date has not been established for the first production of linen in Ireland. 8th and 9th century legends refer to linen worn by people in early Irish society. By the eleventh century, flax—the flowering plant that linen is made from—was being cultivated in Ireland. Government support of the linen industry led to its growth throughout the seventeenth century, particularly in the north of Ireland. So it has been there in a strong way for at over 300 years.
