A very disciplined group of schoolchildren visiting Sydney, on the stairs of the Sydney Opera House. The Opera House was designed by the Danish architect Jørn Utzon and completed in 1973. On June 28th, 2007, it was declared a World Heritage Site, a great honour recognized world wide (except in the German city of Dresden, also a World Heritage Site, but imperiled by a massive new bridge supported by the majority of the citizens) (the region was called "Tal der Ahnungslosen" - valley of the clueless - during GDR times and it still shows...) (please excuse the off topic comment)

Back to the Opera House - it is said it was designed to resemble the sails of a ship, but some people are reminded of a group of disoriented nuns...
