Thousands of people braved the rain Tuesday to see the Tokyo Skytree, reportedly the world’s tallest tower, as it opened to the public.

It is recognized by the Guinness World Records as the tallest tower, beating out the Canton Tower in China, which is 600 meters (1,968 1/2 feet). The world’s tallest structure is Dubai’s Burj Khalifa, which stands 828 meters (2,717 feet). That’s in a different category because it’s a skyscraper, not a tower. The Hindu quoted.

A tower is reportedly considered a different type of structure from a skyscraper because it has far less floor space.

Twice the height of the Eiffel Tower, the new tower is recognized as the second tallest structure in the world at 2,080 feet, behind the 2,720-foot high Burj Khalifa skyscraper in Dubai, United Arab Emirates. LA Times reported.
