This place is pretty big. Lots of halls and rooms. Its almost shaped like the letter E but there are areas that are just open with walls on all sides. This is one of the doors to the courtyard. I never went to shoot outside because of the rain. This building is filled with documents. So many plans and rolls of schematics. Almost like a time capsule in here.
If you decide to go down these stairs..your choices are.. the courtyard, or the basement...
