Peña Negra is one of the main protohistoric sites in the southeast, with a wide sequence from the end of the 10th century BC to the third quarter of the 6th century BC, having been identified with the city of Herna cited in the sources. The site was excavated between the 1970s and 1990s. In 2014, research was restarted, which has made it possible to analyse the transformations of this indigenous nucleus, with new data on the urban planning and ancient topography of the orientalising city, largely due to the direct contact with the Phoenician populations settled at the mouth of the Segura River, making it one of the main sites on the peninsula for analysing the interaction between both ethnic groups.
