The huge collegiate building where, at the moment at which you walk in here, super mutants are fighting synths. You do not find anything of interest here, but it is a good idea to search around for ammo and meds.
1. Roof exit. Apart from a perfect view, you do not find anything interesting here.
2. Second floor. In here, you find a box with lots of ammo, a good armor and a very good shotgun. In the safe nearby (expert level), there is more ammo and technical documentation, connected with a side quest or the Brotherhood of Steel.
