It's part of the Google Cultural Institute's mission to make art and culture accessible to everyone, no matter where they live, through technology. The major collection includes digitised archives, Street View imagery, 50 online exhibits, plus - and this is the best bit - 360-degree insider access into the Opera House as the general public never gets to see it - think backstage between acts, rehearsals for major performances and the Sydney Symphony Orchestra on stage.
The Google Cultural Institute is a not-for-profit arm of the online behemoth and has partnered with over 1000 institutions from 70 different countries to date, digitising over 200,000 artworks, six million photographs, videos, manuscripts and other artefacts since it launched in 2011. This is the first time it's worked with an Australian institution - and we hope it isn't the last.
