The Burj Dubai tower is now 555 metres (1,831.5 feet) tall and has surpassed the 553-metre- (1,824.9-feet) CN Tower in Toronto, Canada, which held the record for the world's tallest free-standing structure since 1976, developers Emaar Properties said in a statement.
The skyscraper, being built by South Korea's Samsung and set for completion at the end of next year, is one of several mega projects taking shape in Dubai, which is part of the United Arab Emirates.
