Somewhat unknown and a total waste of money, we here on the West Coast have our own Space Shuttle Assembly Building, located at Vandenberg Air Force Base, about 50 miles W-NW of Santa Barbara. It is called the Space Launch Complex 6 (SLC-6). The big draw of Vandenberg is that polar orbit is much easier to achieve from that location. However, it is also subject to heavy fog and terrible wind conditions. After the Challenger disaster, the chances of a Vandenberg shuttle launch basically became nill.
The cool thing about the Vandenberg building is that it has two 'halves' that actually move and can closeup together. The Shuttle Assembly Building is 280ft (85.34m) tall and the Mobile Service Tower is 324ft (98.75m) tall.
I've actually wondered over the years if these are the tallest buildings that move (the whole building shifts location)?

The facility has been heavily modified over the years (the mobile tower used to be about 40ft taller) to launch satellites into orbit via rockets. Here's a photo from the recent Delta IV launch, the first of it's kind on the West Coast:
