The famed Sears Tower - 520 metres tall including the twin antennae atop it. That makes it taller than Petronas Twin Towers, or is it? The argument continues, until Taipei 101 comes along. But even Taipei 101 is only 509 metres with its spire.
Anyway, Sears wins when it comes to:
1) Height to the highest occupied floor.
2) Height to the top of the roof.
The observation deck is on the 103rd floor - that's 412 metres up in the sky - and that's where I'm going today. I've been to the 87th floor of 452-metre Petronas Tower 2, and the 45th floor of the 243-metre Tokyo Metropolitan Govt Offices Tower, so this Sears visit should be fun!
