RYANAIR is moving its Irish headquarters from Dublin Airport to a business park in Swords.
The airline has purchased a new 100,000 sq ft office building which will house its main Irish operation including 400 staff.
The new headquarters will be home to Ryanair's commercial, financial, marketing and IT departments.
Some facilities will continue to be operated by Ryanair at Dublin Airport.
"This is a significant investment by Ryanair, allowing us the space and facilities to further develop our Dublin organisation, at much lower costs than the high rents on the Dublin Airport campus," the company said.
