Solgrav is Swedish/Norwegian/Danish for "sungrave" (sol=sun, grav=grave). The name comes from an old Finnish myth. According to this myth there's a place called Auringon Hauta (sun's grave) where the sun falls asleep. Actually a place with this name truly exists, it's a small lake made by a meteor in Estonia.
