The new headquarters for almost 20 sporting bodies have officially opened at a national training centre in west Dublin.
Works on multi-sport all weather pitches and a pavilion are also under way at Irish Sport HQ at the National Sports Campus, Blanchardstown, while sites have been allocated for gaelic games, rugby, soccer and hockey pitches.
High performance training facilities for Horse Sport Ireland and Pentathlon Ireland are also scheduled to be completed by August.
Taoiseach Enda Kenny said the arrival of 19 national governing bodies is a major step in the development of the campus.
"Ireland is a country that is passionate about sport and it is fitting that where possible we should have world class facilities to support, encourage and inspire everyone to get involved in sport," he said at the official opening.
"This Government has put a renewed focus on supporting sporting activities nationwide and I'm delighted that significant progress has been made in the development of the National Sport Campus over the past 12 months.
"Today's milestone will also help foster the sense of community and co-operation which I know already exists in Irish sport."
The anchor building on the campus, the National Aquatic Centre, opened 10 years ago - with the rest of the development continued on a phased basis. Governing bodies which have moved into the new Irish Sport HQ include the Angling Council of Ireland, Gymnastics Ireland and Paralympics Ireland.
Sports Minister Leo Varadkar said the National Sports Campus had been his vision with sport chiefs invited to develop lands and facilities made available.
He said: "The campus is now well on the way to being a national training centre for sport. It shows what can be achieved when you work on a realistic scale, within realistic budgets, in partnership with the sporting bodies."
