This post is about buildings on Penn State University Park (main) campus.
If you want to showcase some buildings on your campus to visitors who are in town, take them to the IST Building - which (to me) looks like a high speed rail station with its long span, elevated position and all glass walls.
If you are into buildings with lot of glass, then the ones on campus you want to check out are:
IST Building, Lewis Katz Law Building, Life Sciences Building, Smeal Business Building and the School of Forestry Building.
The IST building is closer to downtown and easily approachable.
The top pick on campus however goes to the new Lewis Katz Law School simply because of the setting. It is set in the middle of a vast green expanse.
