A plan for the development of the former Maze Prison site has been officially launched by the government.
How the Maze site could look under the new proposals
The proposals for the 360 acre site include a multi-sports stadium and "centre for conflict transformation".
A competition has been launched for the 42,000-seater stadium hoped to be built at the site near Lisburn.
The stadium is the main element of the plan but part of the prison will be retained for the conflict transformation centre.
However, a final decision on the plans could still be 18 months ahead.
The BBC obtained a leaked copy of the "masterplan" four months ago.
BBC NI political correspondent Gareth Gordon said the fact that its publication had been delayed for so long was a sign of problems which could yet derail the project.
NIO minister David Hanson launched the plan, which was attended by representatives from football, rugby and the GAA, the sports which will use the stadium and are also part of the steering group for the development.
The four main political parties were also represented.
As well as outdoor stadium the plan also features an indoor stadium, a hotel, equestrian arena and land for housing and industry.
However, in the end the plan could all come down to money.
