Primark (known as Penneys in the Republic of Ireland) is an Irish clothing and accessories company which is a subsidiary of AB Foods, and is headquartered in Dublin. The company's first store was founded by Arthur Ryan on behalf of the Weston family in June 1962 on 47 Mary Street, Dublin, the store still remains operative to this day.
Success in Ireland led to expansion to the United Kingdom, and the company opened a large store in Belfast City Centre in 1971 and one in Derby, England, in 1973. The company could not use the name "Penneys" in Europe outside Ireland because J. C. Penney had the name registered. The name "Primark" was then invented to use outside Ireland.
Primark opened its current international headquarters in 2015 in a redeveloped Dublin building, Arthur Ryan House, formerly Chapel House.
