LinkedIn has officially opened its new Europe Middle East and Africa building in Dublin.

The 17,650 sq metre building cost €85m and is now home to the 1,200 staff working for the professional networking and recruitment site.

LinkedIn has been in Ireland since 2010 when it opened its first operations here with just three staff.

The company uses its Dublin office to serve the entire EMEA region, through roles in sales, marketing, customer service, finance, analytics and engineering. 

The Irish based workforce is made up of people from 55 countries. 

The office was officially opened by Taoiseach Leo Varadkar and Tánaiste Frances Fitzgerald. 

The purpose-built building has, like many of those housing tech companies here, got a range of special facilities including a music studio, a gym, restaurant, coffee bar, roof terrace and games room.

It is also built to a high environmental standard, with built-in rainwater harvesting, 250 bicycle parking spaces and automatic blinds controlled by a weather station.
