Looks like they were following the Fenway model. Too bad that was perfected about 100 years ago.
Some idiot contractors just did the same thing in the courthouse where I used to work. They built brand new state-of-the-art court rooms, and put giant support beams in the middle of them that totally obstruct the view of a large number of the audience.
(Obviously, I know that trials aren't quite the spectator sport that the NFL is, but still, it's unacceptable that professionals can't design a building.)
