Penneys said it will officially open the doors of its newly relocated store in Dundrum Town Centre on Thursday June 22.
The retailer has invested €14.8m in its new revamped store, which it said reinforces its continued commitment to the Irish market.
Penneys is expanding and relocating to the second and third floor of the former House of Fraser site in the shopping centre which will feature 60,000 square foot of retail space.
The new store marks a 64% increase in size from the current Dundrum Penneys store.
When the new store is open, Penneys will become one of Dundrum Town Centre's biggest fashion stores and the third largest Penneys store in Ireland, following its flagship store in Mary Street and its store in Blanchardstown Shopping Centre, Dublin.
Penneys, which operates as Primark outside of Ireland, currently has 37 stores in Ireland and over 400 in total across Europe and US.
The new store in Dundrum is part of its commitment to invest over €250m in Ireland over the next 10 years, which includes the development, relocation and/or refurbishment of its stores across the country.
The investment also includes a €75m new warehousing and distribution facility in Newbridge in Co Kildare, which is currently under construction.
Damien O'Neill, Head of Penneys Ireland and Northern Ireland, said the new store in Dundrum is an important location for Penneys and very popular with its customers.
"The store is nearly ready and looking incredible - we are confident our customers are going to love our new space and as it's twice the size of our current store, we are excited to offer a much wider selection of products across fashion, beauty, lifestyle, and homeware, including some great new services," he said.
Don Nugent, Centre Director at Dundrum Town Centre, said he was delighted that Penneys has committed to a continued presence in Dundrum Town Centre, and at such prime locations on levels two and three of the shopping centre.
