The Lyric Theatre has won a £250,000 boost to its building fund.
The new theatre will cost £17m
The money is to go towards facilities for young people in the new south Belfast theatre. It has come from the foundation for Sport and the Arts.
It is a welcome addition to money the Lyric has raised to pay for knocking down and rebuilding its theatre on the banks of the River Lagan.
A cheque for a the money was handed over by the film maker Lord Attenborough.
The new theatre will cost £17m and about 70% of that has been committed by public funders.
The rest is being raised by the theatre and in June a local business man donated £1m.
There is still a shortfall of £2m and the theatre hopes to raise most of that before it closes finally in the New Year.
