On Monday, January 4, 2011, UAE Vice President, Prime Minister and Ruler of Dubai His Highness Sheikh Mohammed bin Rashid Al Maktoum officially inaugurated Burj Khalifa, the world's tallest building. The opening coincided with the commemoration of the 4th anniversary of Sheikh Mohammed's accession as the Ruler of Dubai.
In a surprise move, Sheikh Mohammed renamed Burj Dubai to Burj Khalifa - after the president of the United Arab Emirates and Ruler of Abu Dhabi, His Highness Sheikh Khalifa bin Zayed Al Nahayan. Sheikh Mohammed also unveiled a commemorative plaque inside the tower bearing the new name, announcing the official inauguration of the most prestigious tower built on the most expensive square kilometer in the world.
