For a period of time, the World Trade Centre stood as the tallest building in the world, attracting visitors from across the world who came to view this imposing structure.
However, upon the completion of the Sears Tower in 1973, it became the tallest building in the world for 25 years.
Here are 7 of the tallest buildings in the world.
1. Burj Khalifa: The world famous Burj stands at 2,717 feet and houses the world’s highest nightclub, the world’s highest restaurant and the world’s highest observation deck.
2. Shanghai Tower: The first of the entries from China, the Shanghai Tower stands at 2,073 feet and is an eco-friendly building. Popularly referred to as a vertical city, the Shanghai Tower has “neighborhoods” and indoor gardens in addition to its variety of commercial, retail and hotel space.
3. Abraj Al-Bait Clock Tower, Mecca: Located within walking distance of the Grand Mosque, this 1,971 feet tall complex features several towers to house the thousands of pilgrims who flock Mecca. The clock tower displays the four largest and highest clock facades in the world.
4. Ping An Finance Centre, Shenzhen, China: Standing at 1,965 feet, the Ping An Finance Centre is truly a beauty to behold.
5. Lotte World Tower, Seoul: The 1,823 feet tall Lotte World Tower in South Korea's capital hosts a wide variety of tenants ranging from movie theaters to an “officetel" - a mixed residential and commercial zone where people can both work and live.
6. One World Trade Center, New York City: Standing where the former World Trade Centre used to stand, One World Trade Center is 1,776 feet tall- a deliberate reference to the year the United States Declaration of Independence was signed. It is also the tallest building in the Western hemisphere.
7. CTF Finance Centre, Guangzhou, China: This is a taller and younger version of Guangzhou’s twin towers. In 2017, when Rosewood opens a facility on the top 16 floors, it will house the new highest hotel in the world.
