TOP FIVE I FOUND IN Wikipedia.org
1 Taipei 101,
2Petronas Tower I, Kuala Lumpur, Malaysia
3. Petronas Tower II, Kuala Lumpur, Malaysia
4 Sears Tower, Chicago (IL), United States
5 Jin Mao Building, Shanghai, China
I noticed this building was always pointed out or discussed on maps, then I did a search on the internet, but I more or less ignored because, who cares just another tall building.
Then third day into Taipei, I ask someone,
"What is the big deal about this building?"
A person said,
"It is the worlds tallest."
So here I am looking at the official Taipei 101 building, reading maps, and everybody assumes that everyone studies Taiwan...
Therefore I am going to go see this building, now that someone made it clear.
I think this is the official page, not very good at anything, unless you want to rent an office.
This one is sort of fun.
