Etruscan habitation sites in the area of Siena that are contemporaneous with La Piana, such as Cetamura (see Nancy de Grummond, “Excavations at Cetamura del Chianti, 1987–91,” Etruscan Studies 1 [1994], n. 2 and “Excavations at Cetamura del Chianti,” Il Chianti, Storia Arte Cultura Territorio 15 [1991], pp. 67–68), Orgia and Radda in Chianti (see Marzio Cresci and Luca Viviani, Lo scavo dell’insediamento fortifcato d’altura in località Poggio La Croce a Radda in Chianti [Siena, 1991] and “Defining an Economic Area of the Hellenistic Period in Inland Northern Etruria: The Excavation of a Fortified Hilltop Village at Poggio La Croce in Radda in Chianti—Siena,” Etruscan Studies 2 [1995], pp. 141–157), and tomb sites, such as Malignano (see Kyle M. Phillips, “Malignano,” Notizie degli scari di Sc [1965], pp. 11–29), Papena (see Kyle. M. Phillips, “Papena [Siena]. Sepultura tardo-etrusca,” Notizie degli scari di Sc 21 [1967], pp. 23–40), Strove (see D. W. Rupp, “The Necropolis of Strove: Preliminary Report of the 1967 and 1968 Campaigns,” Etruscans 1 (1967–69), pp. 27–39), and San Martino ai Colli (see Giuseppina C. Cianferoni, et. al., San Martino ai Colli, un centro rurale in Val d’Elsa [Rome: Edizioni Viscon Viella, 1984]), which hint at the presence of as yet undiscovered settlements, document this expansion.
