Nicknames

 When most people hear the iron lady they think of Margaret Thatcher but there's another Iron Lady that is aka the Eiffel Tower. She (yes the tower is of the feminine persuasion) has had several nicknames before locals settled on the Iron Lady. The Sydney Opera House was designed to look like the sails of ships but the locals affectionately refer to the building as "Nuns in a Scrum" because it looks like a huddle of rugby players and the white coiffes worn by Catholic nuns. The Sydney Harbor Bridge also has an  interesting nicknames, the Coat Hanger and the Anzac Bridge also in Sydney is known as  Madonna's Bra.
