Sydney Opera House alterations, 2006 / photographed by Jeremy Piper2006In 2006, the first alterations to the exterior of the Sydney Opera House were made since its 1973 completion. A colonnade was constructed as part of Jorn Utzon's original vision. Utzon was credited with involvement in the project, however architectural historians and journalists were critical of the colonnade and believed it compromised the impact of the Opera House overall. Nevertheless, the Opera House achieved World Heritage recognition in 2007.
