Science building, SF State (San Francisco)

Home to many classrooms and faculty offices, this labyrinthine building is one of the campus' oldest structures. It was built in three phases, leading to jarring differences in architecture, and staircases that lead nowhere. It is also one of two locations on campus where university students can rent lockers.
Its name is mostly vestigial, as few of the occupants of Science are sciences. Sciences are mostly in nearby Thornton and Hensill.
