The campaign will go live next month, to coincide with the Rugby World Cup.
Cork Jazz Festival
The aim of the campaign is to encourage French holidaymakers to fly or sail direct to Cork during the off-season months.
Filming for the campaign took place at various locations, including Charles Fort and The Bulman in Kinsale, as well as in Cork city at The English Market, The Farmgate Café, Crawford Art Gallery, Patrick Street and Market Lane.
The crew also captured footage of musicians from the Cork Jazz Festival and of an oyster experience in Goldie.
Rugby World Cup
The campaign will include a new video featuring O’Gara visiting various locations in Kinsale and Cork city that ‘fill his heart with Ireland.’
As well as being a Cork man, O'Gara is a manager of French rugby side La Rochelle.
“It’s a great opportunity to capitalise on the excitement in the run-up to, and during, the Rugby World Cup," said Monica MacLaverty, Tourism Ireland’s manager Southern Europe.
"Our aim is to highlight the many great experiences and attractions in Cork city and county, as well as the ease of access from France to Cork and the warm welcome that awaits our French visitors.”
