That’s right… The CN Tower has been surpassed in height by a Dubai building, under construction. This means the CN Tower no longer holds the title as “the world’s tallest building”. The Burj Dubai, a US$4.1-billion hotel, business, and residential complex under construction in the United Arab Emirates, yesterday reached slightly above the CN Tower’s 553-metres.

The Burj Dubai is expected to reach even higher as construction continues, and a soaring 800-metres when finally complete. 145 floors have already been complete in the building, where a new floor is put up about every three days. The complete Burj Dubai is expected to have 165 floors.

The CN Tower held “the world’s tallest building” title for the last 31 years. Completed in 1974, the CN Tower cost $63-million CAD to build, and its construction took 40 months. The tower’s primary function is a broadcast transmission facility. The tower also has a revolving restaurant, and is one of Toronto’s main tourist attractions.

The CN Tower draws nearly 2-million visitors every year. The CN Tower is also recognized as one of the modern wonders of the world by the American Society of Civil Engineers.
