Overnight, the CN Tower in Toronto lost it's status as the world's tallest free standing structure. It has held the record at 553 metres (1,824.9 feet) for just over 30 years.
No, it didn't fall down.
It was surpassed by the Burj Dubai tower under construction in Dubai, which reached the height of 555 metres (1,831.5 feet) yesterday.
The Dubai skyscraper will eventually reach the mind boggling, gobsmacking height of around 800 metres. The actual finished height is being kept secret for now. It'll have 165 storeys of apartments, shops, hotel rooms and office space.
