NTNU was created by the merging of NTH (the Norwegian Institute of Technology), AVH (the College of Arts and Sciences), Vitenskapsmuseet (the Museum of Natural History and Archaeology), the Faculty of Medicine (DMF), and the Trondheim Conservatory of Music. While technology and natural science form a big part of the university's courses (it's the only university in Norway to offer master-level education and doctorates in a broad range of technological studies), the humane sciences also are a big part of it.
The museum is spread across several campuses, with technology and natural science concentrated on Gløshaugen (which is basically downtown Trondheim), while the humane sciences are at the Dragvoll campus, which is a bit further away (20 minutes by bus from downtown and 10 minutes by the same bus from two of the major student housing complexes, with (when I was there) at least eight busdepartures per hour each direction during the workday Monday-Friday). Bicycling is also possible.
There is some measure of resentment at Dragvoll over what they perceive as imbalanced spending in favour of Gløshaugen, and according to Universitetsavisa
there are some space problems at Dragvoll - many students, and not quite enough workspace for all (each master student is supposed to have a permanent readingplace in one of the reserved readinghalls, but there aren't enough to go around, and there are too few spaces in the open reading halls, too).
My impression of NTNU is generally good, though I studied at Gløshaugen. I did have one subject at Dragvoll, though, and it seemed good enough to me. In my experience, teaching at NTNU is perfectly good, though I think the University in Oslo is considered to be better on international ratings. Complaints seem to be more about the physical nature of the campus - not quite enough space, and the layout of the campus at Dragvoll is somewhat confusing when one is new there.
