Sydney Opera House celebrated its 50th birthday on Friday, with a laser show planned to illuminate the iconic building. Officially opened by Queen Elizabeth II on 20 October 1973, the Opera House is widely regarded as one of the greatest architectural designs of the 20th century, with 10.9 million people visiting every year. The building will be illuminated on Friday evening by a light show created by Australian audio-visual artist Robin Fox, before welcoming an expected 37,000 people on Saturday for free tours, its first open day in eight years.
The half-century celebrations are well underway. Meet Leonie Bell, who started working at the iconic landmark the very year it was formally opened by Her Majesty Queen Elizabeth II!
