This is the only Bronze Age cist necropolis in Western Andalusia that is listed as a museum.
The necropolis of La Traviesa, located to the west of Almadén de la Plata, was discovered in 1986 and excavated in 1992 and 1993. It is one of the largest Bronze Age necropolis (2,250 to 1,000 BC) in the southwest of the Iberian Peninsula. It consists of 29 cist burials.
A cist (coffin or box) is a small, individual megalithic funerary monument. It consists of a quadrangular pit in the ground lined with vertical and horizontal stone slabs (flat stones). It forms a chamber in which a body was placed in a foetal position.
It has been declared a Spanish historical heritage site and listed in the catalogue of archaeological sites in the province of Seville.
