The Faculties of Engineering Science and Technology, Natural Sciences and Technology, and Information Technology, Mathematics and Electrical Engineering are all found here. Gløshaugen is also home to NTNU's first building, the Hovedbygningen (the Main Building), completed in 1910, and Realfagbygget, the natural sciences building, opened in 2000. Realfagbygget covers approximately 60,000 square metres, and is the largest building in Trondheim.Seven cafes and cafeterias serve hot drinks and a variety of food throughout the day.
Libraries abound - Three of NTNU's 11 libraries are located at the Gløshaugen campus – the main Technology Library, the Architecture, Civil Engineering and Product Design Library, and the Natural Science Library.
Find the unexpected - The campus is full of surprises, not the least of which are two functioning locomotives, the Ohma Electra, an electric locomotive that's parked next to the Old electrical engineering building, and the Bjørkelangen, a steam locomotive that's parked next to the Varmeteknisk, Thermal energy building. Although the days are long gone when being an engineer just applied to operating locomotives, it seems fitting to find these reminders of the past at NTNU's main engineering campus.
Dragvoll is the main campus for the Faculty of Humanities and the Faculty of Social Sciences and Technology Management, along with the Dragvoll Library, the main library for the arts, social sciences and humanities. The Dragvoll campus is divided into 12 buildings ("bygg") that are linked by "streets" that are glassed over, like a greenhouse, a design that resulted from an architecture contest in 1969. Three separate buildings, called pavilions, house the Centre for Rural Research and NTNU-Videre (Pavilion A), a private research company owned by NTNU called NTNU Samfunnsforsking AS (Pavilion B) and the Norwegian Centre for Child Research and the Department of Education (Pavilion C). The Dragvoll Sports Centre is located behind the pavilions, and contains two training halls, a gymnasium, a weight training hall, three squash courts, a climbing wall and a number of other facilities. SiT, the student services group, also has five cafeterias or kiosks where you can purchase food, along with a bookstore.
The southern part of the Gløshaugen campus, down by the Rosenborg football club's stadium, is called Lerkendal/Valgrinda, and is home to a number of buildings occupied by SINTEF, Scandinavia's largest independent research institute, and a frequent partner in NTNU's research projects. Many SINTEF researchers also teach at NTNU, which is not surprising when you realize that the institute was a spin-off from NTNU's predecessor, NTH, in 1950. This campus is also home to the departments of Petroleum Engineering and Applied Geophysics, Production and Quality Engineering, and Hydraulic and Environmental Engineering, as well as the Valgrinda Library and NTNU Technology Transfer.
Tyholt may be the most visible of NTNU's campuses, simply because of the colourful 120-metre high telecommunications tower that can be seen from throughout the city. NTNU's buildings at Tyholt may be somewhat less colourful than the tower, but they are every bit as impressive, for it's here that you'll find the Department of Marine Technology, right next to the Towing Tank, Cavitation Tunnel and the Ocean Basin Laboratory. The ocean research facilities are technically owned by MARINTEK, a branch of SINTEF, but are used widely in NTNU research. The Marine Technology Library, which is also shared between NTNU and MARINTEK, is also located here, as is a SiT cafeteria.
Kalvskinnet, on the southern fringe of Trondheim's downtown, is home to the university's NTNU University Museum, as well as the Gunnerus Library, Norway's oldest scientific library. The library focuses on archaeology, botany, and zoology, but contains other natural science-related books. SiT has a Tapir bookstore and a cafeteria here as well.
Down on the waterfront you'll find NTNU's own Sealab, or more formally, the NTNU Centre of Fisheries and Aquaculture, a shared research facility right in downtown Trondheim. Four of NTNU's seven faculties have research programmes here. SINTEF's Institutes of Fisheries and Aquaculture and Materials and Chemistry also have representatives here too.
Øya, a little peninsula just outside of downtown Trondheim created by the wanderings of the Nidelva River, is where you'll find St Olavs Hospital, the main tertiary care hospital in mid-Norway. Not surprisingly, NTNU's Faculty of Medicine is located here, with a host of research facilities, including the Kavli Centre for Systems Neuroscience/Centre for the Biology of Memory . SiT operates three cafeterias throughout the campus.
Olavskvartalet features Trondheim's own concert hall, Olavshallen, where the Trondheim Symphony Orchestra regularly performs, and where NTNU's Department of Music has its music performance studies and music technology programmes. The Trondheim Academy of Fine Art is located across the Nidelva River from Olavshallen, in a fine building that also houses the academy's gallery.
NTNU also has a number of far-flung research facilities, including the Ringve Botanical Garden, next to the Ringve Music Museum in Lade, the Department of Biology's Trondheim Biological Station, right on Trondheim fjord to the west of the city itself, and the Kongsvoll Biological Station, nearly three hours by car to the south, on the fringe of Dovrefjell National Park.
