Ragnvald’s Grav, also known as Ragnvalds Kull, Ravarehögen, or Karleby, in Karleby socken in Falbygden, Västergötland, is the largest passage grave in Sweden. It was constructed between 3500 and 2800 BCE as a megalithic structure of the Funnelbeaker culture. This structure represents a type of construction from the late Neolithic period, consisting of a chamber and a structurally separated, lateral passage.
