Portrait of Jørn Utzon - Sydney Opera House Architect

Jørn Utzon was a relatively unknown 38 year old Dane in January 1957 when his entry was announced winner of the international competition to design a ‘national opera house’ for Sydney’s Bennelong Point.

The building transformed his career and, in turn, transformed the image of an entire nation.
