I was reading a post on Facebook about the Sydney Opera House and I did a google search to see what the real story is. It turns out to be a highly unusual and one of a kind design. There is absolutely nothing like this in the world. Please read the 2018 news article which goes into detail, it’s well worth reading and rather educational. It is built within a man made sandstone cavern 42 metres deep.
The government of NSW kept this secret from the public while under construction as the Sydney harbour tunnel was also under the at the same time. Millions of dollars were invested in both construction works at the same time.

Who was Bennelong? https://en.wikipedia.org/wiki/Bennelong The early settlers had no concept of cultural sensitivity which understandably we find offensive today. Life could have been so much better had the white peoples put more effort into understanding the aboriginal people’s culture and spiritual values.
