In the middle of Svartrå are these magnificent mounds of stones. One could easily take them for ancient remains, although it is no ruin but artfully created mounds. They were laid by Nils Jacob Zachariasson between 1893 and 1907. Jacob lived on the nextdoor farm, Gunnagård, with his wife Anna Charlotta, between 1882 until his death in 1923. Today Gunnagård is a visitors’ attraction, with a café and activities for children. Park in the farmyard and walk over to Gunnagrotta, which is visible from the gravel road. Be careful not to trample any growing crops on your way up to the mounds.
