Trondheim is the 3rd largest city of Norway. The university NTNU together with the SINTEF research institute leads the world in many technology-based research areas. Nidaros Cathedral is one of Trondheim's most famous tourist attractions and is worth a visit.

The venue for the Symposium will be Clarion Hotel Trondheim. 19 meeting rooms - with a capacity of 1800 participants for the largest one – make Clarion Hotel one of Scandinavia's largest convention centers. Discover the view on the fjord, enjoy the modern Nordic design and the vibrant atmosphere.
