The Etruscan name of the town is not known; Acquarossa, the name given to the site by the archaeologists, derives from the ferruginous stream nearby.

The site has been excavated by The Swedish Institute of Classical Studies in Rome and the Swedish universities of Gothenburg, Lund, Stockholm and Uppsala, in cooperation with La Soprintendenza per L’Etruria Meridionale. For a number of years, the then King of Sweden, Gustaf VI Adolf, was one of the participants.

The large-scale excavations in the late 1960s and early 1970s were followed by smaller investigations and by work in store-rooms and publication of the finds and findings, which are to a large extent exhibited in the Museo Nazionale Etrusco in Viterbo, Rocca Albornoz.
