Archaeological phases, from the early to late Neolithic, reveal evolving structures and cultural artifacts. Nearby, the Serra de Rodes and Cap de Creus boast a concentration of dolmens, illuminating the region's megalithic heritage. Ca N'Isach offers a remarkable window into Neolithic life, with a rich history spanning millennia.
