The Melbourne Town Hall has been used as a civic and entertainment venue since 1870. Queen Elizabeth II took tea here in 1954, and the Beatles waved to thousands of screaming fans from the balcony in 1964. Take the free one-hour tour to see the Grand Organ (built in 1929, and largest grand romantic organ in the southern hemisphere), sit in the Lord Mayor's chair or tinker on the same piano Paul McCartney did. It's a busy venue during the Melbourne International Comedy Festival.
