This is a John Utzon's amazing architecture "Sydney Opera House." It has a such a spectacular concreted shell roofs that truly combines with the harbour aquatic environment. Its completion was at 1973 and opened at 20 October 1973. I quite often visit this place, walking around the Circular quay Wharfs and observe this buildings from different directions and observe the area. During the night, a different genres of lighting always provides something different and unexpected gorgeous scenery of Sydney.
