They were created for practical reasons, like the cemetery of Grebine, when many inhabitants died of cholera (unknown century) during summer grazing at Rujno. As Rujno is a two to three hour hike from the village cemetery on the coast, it was physically impossible to bury the dead in the latter. When the epidemic died off , both the mirilo site and the upland cemetery were abandoned. Only the toponyms Grebine and Mirila survived. Two fallen megalithic headstones are preserved. One bears a cross of interesting iconography, which is the only one such known. The three upper arms are three-branched, and the lower arm has a square tripod shape. This headstone should be protected in a museum because of its monumental nature and the decoration.
