"Borne out of this, starting around the 17th Century was the Baroque era. It is my view that it is one of the architectural peak periods in western civilisation"

The quote by Harry Seidler is referring to the Baroque era, which started around the 17th century. Seidler is expressing his opinion that the Baroque era was one of the most considerable durations of architectural development in Western civilisation. The Baroque era was a period of excellent artistic and architectural innovation, with a focus on grandeur and extravagance. It was characterised by elaborate and sophisticated styles, typically including detailed details and bold colours. The Baroque period saw the emergence of a few of the most iconic and prominent structures in history, such as the Palace of Versailles and the Taj Mahal. Seidler's view is that the Baroque age was a period of great architectural achievement, and among the most important periods in Western civilisation.
