While it was originally planned to reopen in time for the centenary on 25 May 2008, delays prevented this, and the house was finally reopened with a gala concert and 3D animations on 24 May 2010, the eve of its own 102nd birthday and the Argentina Bicentennial. Tchaikovsky's "Swan Lake" and Act 2 of Puccini's "La bohème" were performed. A private concert to test the acoustics attended by employees, architects, and others involved in the renovation occurred on 6 May 2010.
