"Nothing symbolizes Sydney quite like the Jørn Oberg Utzon-designed Sydney Opera House that lords over the Sydney Harbour with its shining, bright white concrete shells. The UNESCO World Heritage Site was completed in 1973, marking 2023 as its 50th birthday. The festivities run from the beginning of September to the first week of November and feature loads of musical performances, plays, dance recitals, talks, and more. Multiple events are ticketed, but there is plenty of free entertainment as well. Join in on the fun at one of the world’s greatest architectural marvels during this golden jubilee celebration." - Travel + Leisure Editors
