The beloved sportswear shop, also known for retailing uniforms, will cease trading before January 30.
At the helm of the successful enterprise is former international rugby legend, Moss Finn and his brother, Irish Angler, William Finn.
The shop regularly sold denim jeans to 'local' musician, the great guitarist Rory Gallagher, and also supplied and sent rugby boots to All Black legend Jonah Lomu, after Adidas once ran out of pairs in his size.
Speaking about the closure, Moss lamented the end of an era and thanked the people of Cork for their support.
"Myself and William are at retirement age, so that's the reason we've decided to close.
"We could definitely have kept going as business is good and we have the people of Cork to thank for that.
"Of course it's sad, but we're going out on our own terms.
"I'd like to thank the people of Cork for their goodwill, great sentiment and profound generosity," he said.
"We've faced challenges over the years like any business, but the loyalty of the people of Cork has seen us through," Moss continued.
As well as a loyal cohort of customers, the staff at Finn's Corner have been extremely devoted to the success of the business over the years - most notably John Dwyer who has worked in Finn's Corner for the past 52 years.
The sale has been agreed on the five-story property, located on the corner of Grand Parade and Washington Street, according to estate agent, Cushman & Wakefield's website.
The building has a rich and diverse history, built in the 19th century and significantly redeveloped in the 1990s.
Throughout the decades, countless famous faces have graced the building.
"Charles Stewart Parnell once gave a speech from the building's second floor, where he addressed the assembled crowd below.
"The history of the building is incredible," Moss explained.
Following the news of their closure, several Cork businesses, including the Maldon Hotel, Bradley's Off Licence and Pinocchio's Toys have taken to social media to express their regret at the loss of the independent business.
Additionally, women’s clothing store ONLY on Opera Lane has ceased trading.
The closure of the retail unit located between Specsavers and Next was anticipated after the business announced a clearance sale a number of weeks ago.
ONLY is an international brand, with thousands of stores worldwide.
In Cork, there is also an ONLY store in Mahon Point, which remains open.
