Due to a 1971 merger with the rural districts of Hermansby, Kode, Romelanda and Ytterby, as well as Marstrand town, the town of Kungälv has considerably increased. This also means that many of the local historical societies are now placed within Kungälv`s district.
The local historical movement, in the countryside, had already begun by the early 1900`s but it really lifted off after the World wars and many societies were formed in the 1950`s.
It is thanks to the those dedicated people who put in thousands of voluntary hours, working with building conservation, article collecting and documentation that we today have a large number of old homestead museums within the district of Kungälv. They also work with preserving traditions by promoting several arrangements like; cultural wanderings, a Midsummer celebration, film and lecture evenings and local historic days.
