Trivia: A famous opera house defines the skyline in what Southern Hemisphere city?
Correct Answer: Sydney
So why is this answer correct? : The skyline of Sydney, Australia, includes buildings like Crown Sydney, the Chifley Tower, and the Citigroup Centre, but its most recognizable feature is only 222 feet tall. The Sydney Opera House, which opened in 1973, is one of the most famous and distinctive buildings of the 20th century. Designed by Jørn Utzon, who won a contest for the contract, the Opera House holds a few performance venues, the largest of which is a 2,679-seat concert hall.
