The Torraca is very rare and is specific to the Salerno and Potentino areas. Latorraca is a little less rare and specific to the area that includes Basilicata, Bari and Taranto, and should derive from the toponym Torraca (SA).
Torraca is specific to Salernitano, Gioi, Salerno and Orsaia Tower, with a strain also in Naples and in Grumento Nova and Spinoso in the Potentino, should derive from the name of the town of Torraca in the Salernitano. Additions provided by Giovanni Vezzelli Torraca is the surname Campania and Lucano which means "ancient tower" from the Latin ' turris ' = "Tower" and Greek ' archè ' = "Ancient", fusion due to the presence of the two classical cultures, the Latin and the Greco-Byzantine. It probably derives from the toponym Torraca (SA). It seems that the country had been rebuilt in the late Middle Ages at the remains of an ancient Lucano village. A group of inhabitants of the coast came here to build a safer seat from the Saracen incursions, and they called Torraca the place. In ancient documents also appears as Turraca.
