Completed in 1889, this building dominated the Sydney skyline for over a century and is considered the most daring and technologically innovative during this time. Its Centennial Hall is constructed with extravagant scale and size, featuring Tasmanian blackwood and tallowwood floor and the famous 25 metre wide Grand Organ, which spans the entire width of the western wall. There are 21 stained glass windows featuring Australian flora, a stunning ornate ceiling and twelve giant marbled pillars in the corners of the Hall.
