The mounds and heaps of stone were characteristic of both this and the wider region, in the form of tumuli as part of a fortifi ed system of walled settlements and places of ritual. They were always situated in the vicinity of hill-fort locations, at strategic places, along communication lines, above fi elds, and most of all, along cliff edges.

The largest necropolis of cairns, not only in the area of the Dubrovnik Coast, but also in the entire southern Adriatic region, is between the settlements of Visočani and Lisac, where 48 cairns have been recorded.
