Facebook looks set to create hundreds of new jobs in Dublin.
The social network has been based in the capital since 2009 - and Sonia Anne Harris, the head of Facebook in Ireland, has posted on the site saying they are now moving to a "much bigger" premises in Grand Canal Square.
She said that when the new HQ opens, she believes Facebook will be able to "invite hundreds more talented people" to join the staff.
The new office has the capacity for 1,000 workers - more than double Facebook's current workforce.
Facebook says the new premises will allow them to expand in areas including database engineering, marketing and advertising sales.
