Nidaros Cathedral is located at Bispegaten 5 (73/53-91-60) and is an exquisite building that was constructed in the 11th century. Positioned in the center of town, Nidaros is known as one of the most important cathedrals in all of Scandinavia. Many Norwegian kings have been buried here throughout the centuries, and it was here that modern Norway was born. Haakon VII had his coronation at Nidaros, completing a series of events that truly established Norway as it is today. The diverse architectural styles are incredible, and set against the Trondheim skyline, the Nidaros Cathedral is breathtaking. Both Romanesque and Gothic features are present, and the gargoyles on the main tower are spectacular. Inside you will find an interesting little museum where Norway's crown jewels are on display. Right behind the cathedral is the Archbishop's Palace, which was completed in the 12th century.

The Museum of Natural History and Archaeology is located at the Norwegian University of Science and Technology (73/59-21-60). An incredible number of interesting topics are explored here, making it a must see if you are in Trondheim. The museum focuses on the social history and natural history of Norway, with archaeology being heavily represented as well. The displays of animals of ancient Norway are wonderful, and everything is extremely well-executed and maintained. The dioramas are modern and lifelike, and there is even a collection of old church art that is wonderful. The museum concentrates on encouraging mutual support between man and nature. One exhibit chronicles the history of man in nature, how it has helped him, and how he has abused it. There are plenty of great things to do in the museum to keep you enthralled for hours.
