 Excavations conducted by the University of Florence on the Santa Teresa estate between 2004 and 2007 discovered five gravestones used between the mid-7th century BC and the second half of the 6th century BC, surrounded by many farms.The results of these operations show a high percentage of households owning graves.In addition to agricultural resources, the population took advantage of the benefits of their strategic position which allowed control over the flow of minerals to the manufacturing center of Vetulonia.
