Sydney Town Hall stands as a magnificent sandstone structure that serves as the gateway to the city center. Built in the 1880's, the hall has served as the center of the city government and also served as the primary concert hall of the city until the Sydney Opera House was completed. Town Hall is also the only non-religious building in the area from the 1800's to maintain its original purpose. Sydney's Town Hall is also home to the world's largest pipe organ which contains one of only two 64 foot organ stops in the world. Visiting the hall is a great way to immerse yourself in the history of Sydney.
