Sillaro


The Sillaro is a long Italian stream, whose headwaters are by the village of Piancaldoli, in Tuscany. It runs northeast through the city of Castel San Pietro Terme, Province of Bologna in Emilia Romagna. The river runs through a short extension of the province of Ravenna extending into the province of Bologna before re-entering the province of Bologna. It then forms the border between the province of Ferrara and the province of Ravenna for a short distance before entering the province of Ferrara. The river ends as a tributary of the Reno River by the village of San Biagio di Argenta and near where the Idice enters the Reno. Historically its course formed the boundary between Emilia and Romagna.
