The Trøndelag Folk Museum is located on the outskirts of the city, near a forest and it is an open-air exhibition of all the most significative houses and stave churches of Norway, especially from the area.
You can see how local architecture changed through the centuries, as well as according to the landscape (fjord, mountains). There are over 60 houses in the park, including the ruins King Sverre’s castle and the amazing Haltdalen Stave Church, dating back to 1170.
This museum is a bit out of town. It is a collection of houses moved here from various places in Trøndelag.
The historical grounds in front of Norways first ever stone fortress is also daunting. Imagen, if you can, a fortress on the bear rock when you get here. If you climb up you will see the ruins of the fortress.
You can also see the exibition inside showing life in Trøndelag. It's organized kronologically from birth to death of ordinary people.
