It's got a long-term lease in Dublin 4

Facebook is expanding its Irish operations, with the potential to add 5,000 jobs.

The social media giant has acquired a long-term lease of 14 acres for a new development at the Bank Centre in Dublin 4.

This building is currently occupied by AIB.

It'll see Facebook quadruple its current floorspace across a number of buildings.

By the end of 2018, there'll be over 4,000 people working for Facebook in Ireland across four locations.

It also owns Instagram, WhatsApp and Oculus.

Facebook’s international headquarters is in Dublin's Grand Canal Square, and it also has operations in the Samuel Beckett Building, a data centre in Meath and Facebook Reality Labs in Cork.

In a statement, the company says: "Ireland is critically important to Facebook and plays a central role in its global operations as home to over 60 teams including engineers, safety experts, legal professionals, policy experts, marketing and sales teams covering many facets of the social network."
