The lords of Prata hold the lowland between the Livenza, the Meduna and the Noncello on the Treviso border.
Porcia, whose castle is documented from 1178 and which appears as the 'curia de Purciliis' in 1199, still belongs to the Prata territory on 1 January 1200: the two Prata brothers divide their estates about 1203 and fix the boundaries in 1214, when Porcia becomes a separate fief of some twenty villages. The house took part in the struggles for mastery of the Trevisan and Friulian borderland, and Treviso claims to have subjected the da Prata after the Peace of Constance (1183).
