Strutture megalitiche del Sahara settentrionale (Chott el Jérid, Tunisia)

Abstract

Megalithic monuments are a distinctive archaeological feature of Saharan landscape, as indicated by different systematic research projects undertaken so far. Starting from a very low baseline of previous archaeological research, and as part of a comprehensive research programme focussed on northern Sahara, we launched in 2015 a territorial investigation of stone monuments of the pre-protohistory and early history of southern Tunisia. To do this, we selected a sample study area east and south-east of the Chott el Jerid depression (Kebili region) where to conduct field research. In this paper we present the research strategy adopted, planned to address some issues such as the poor state of preservation of the monuments or their uncertain chronology, also known from other parts of the Sahara. Our results, based on the combination of remote sensing analysis, field survey and selected excavations, highlight a dense occupation of this area of northern Sahara, where monumental buildings of possible funerary function tentatively trace back to the late pre-protohistory up to the roman age. The persistent use of the area across a long-time span corroborates its pivotal location in ancient trans-Saharan connection routes.
