There are several known instances of megalithic graves being rebuilt and reused already in prehistoric time. The aim of this study is to investigate the phenomenom of megalithic reuse through the theorethical framework of social memory. Focus lies on two graves in southern Sweden; Firse sten in Falbygden and Skepparsl?v 10 in Scania. The two graves were originally constructed as passage graves but have in different ways been remodified into gallery graves.
