OSTIA: PORT OF VALTARO
Ostia Parmense (from ostium, door), has been already inhabited by Protoliguri Bronze Age (XVsec a.C.). Traces of settlements have been found at Gorro, Groppo to Tornatore of Roccamurata on Taro, and on the right bank of the river Cogen, which in Ostia, flows into the Taro.
We have found the remains of pottery, deer and bear bones.
They also had a function of controlling the territory, due to the morphological characteristics of the zone. In fact, even in the following centuries the access to Valtaro is made difficult by the natural tight spot of Roccamurata-Ostia.
In fact, the connecting roads between the Po Valley and Lunigiana and the sea used: or steps to the west like the Borgotaro Borgallo, Brattello and Two Saints, or the route of Mount Bardone, the current Cisa Pass.
The defensive position is then manifested in the Dark Ages, when probably the Byzantines, in order to prevent the conquest by Lombards Valtaro allocated to the Castrum Neblo of Solignano, built a fort on the left side of Taro to Roccamurata, upstream of the back of Tornatore.
This fortification was part of a group of "turres", perhaps both of the cheek, head of the "limes" or boundary between the Lombards and Byzantines. The more important "Turris" was located in the foothills of Val Vona, on the left side of the Taro river, to the height of the Borgo Val di Taro.
Conquered by the Lombards in 644, the Valtaro, Ostia became part of the "comitatus torresianus" division centre of “exercitus italicus "and then the goods of the Abbey of Bobbio, founded in 612 by St. Columban Irish Monaco, to which lands belonging to the Royal Treasury were given.
The torrent Cogen sawed the division between gastalds of Parma and Piacenza, whereas in neighboring Baselica had jurisdiction, the Diocese of Luni, as Valdena and Albareto.
Probably a branch of the route of the Abbots of Bobbio leading to Rome, passed from passage of the Borgallo or Val or Val Mozzola Vona.
The church dedicated to St. Michael the Archangel, was destroyed in the sixties, , which suggests it was part of that important route leading from Mont Saint Michel in France to Gargano, where the pilgrims embarked for the Holy Land.
The church was under the parish of Berceto, even if belonging to the Cathedral of Pavia, to which it paid the tithes. With the arrival of the Franks it became part of the Parma Comittee and followed the fortunes of the City of Borgotaro which was discussed for the first time in Registrum Magnum of the City of Piacenza in 1195.
After the Malaspina and Piacenza, the Land, Fieschi, the Farnese, the Duchy of Parma and Piacenza with Marie Louise, wife of Napoleon followed. Thanks to Mr. SANDRO SANTINI, author of the texts.
