Lurekalven is an unpopulated island of heather moor which is a part of the wilderness belonging to the five farms on Ytre Lygra. Between the two islands there is only a small sound. As late as the 1920s, milking cows were rowed over the sound from Lygra in summer – a form of farming that was adapted to the coastal landscape.
The biggest collection of prehistoric burial relics in Stord is to be found in Hystadmarka. There are still 16 burial mounds and two stone rings visible here; finds that span from the Bronze Age to the Viking Age in time.
