Many of the world's most famous buildings sport spires, masts and other bullshit designed to make them superficially taller without adding to the expense and difficulty of construction.
Pictured below is the classic example: The Petronas Towers, which captured the title of "world's tallest building" from Chicago's Willis (then Sears) Tower in 1998 despite being obviously 60m shorter.
This video shows the world's towers appropriately denuded of their dirty, lying spires.
