: Burj Khalifa the tallest building in the world

In a compition to make world’s best monuments around the world, dubai has toped all this odds and built many of them despite the fall of financial conditions in recent months.
In a row dubai has built its first 7 star hotel in 1994 (burj al arab), first longest driverless metro train in 2009 and now the world’s tallest building which breaks many of the records that a building had in the past.
here are the details as we fetched from the online resources:

The Burj Dubai (Burj Khalifa) tower officially opened its doors on January 4, 2010, six years after the commencement of construction in Dubai, United Arab Emirates.

The economic hardship and debt crisis has caused the building to stand mostly empty and unwanted by the international tenants for whom it was supposedly built. An article in Wall Street Journal sees the Burj Dubai “a modern-day Tower of Babel”.

The race to construct bigger structures and show the economic might will never stop. It is to be seen for how long the ‘tallest’ status or other records could hold.
