[Photo] Tallest Building in South Korea and 5th Tallest in the World

A couple of days ago, I've visited the Lotte World Tower, the tallest building in South Korea and the 5th tallest in the world.

It has 123 floors and boasts the world’s highest glass-bottomed observation deck and the world’s fastest elevator. From the bottom to the top, it takes only one minute!

Unfortunately, I couldn't go to the observation deck because it was extremely crowded, so I just took a picture from the bottom:

I think I would feel dizzy at the top...what about you? :P
