Which Sydney landmark was one of the first to join the Global Greening for Saint Patrick's Day?

The Sydney Opera House was one of the first landmarks to join Tourism Ireland’s Global Greening Initiative for Saint Patrick’s Day. It participated alongside Auckland’s Sky Tower when the international campaign began in 2010.

The initiative illuminates prominent buildings and sites in green to celebrate Irish culture and connect communities around the world with Ireland’s national day. The Sydney Opera House was an especially striking participant because its distinctive white shells create a dramatic contrast when bathed in green light. Its location on Sydney Harbour also makes the display highly visible in photographs and broadcasts.

The Sydney Harbour Bridge is an understandable alternative because it is another internationally famous Sydney landmark and has also appeared in major lighting campaigns. The quiz’s historical clue is narrower, however: the Opera House belongs to the original group of landmarks that helped launch the global greening tradition.
