博洛尼亚省
Bologna is situated on the edge of the Po Plain at the foot of the Apennine Mountains, at the meeting of the Reno and Savena river valleys. As Bologna's two main watercourses flow directly to the sea, the town lies outside of the drainage basin of the River Po. The Province of Bologna stretches from the western edge of the Po Plain on the border with Ferrara to the Tuscan-Emilian Apennines. The centre of the town is above sea level (while elevation within the municipality ranges from in the suburb of Corticella to in Sabbiuno and the Colle della Guardia). The Province of Bologna stretches from the Po Plain into the Apennines; the highest point in the province is the peak of Corno alle Scale (in Lizzano in Belvedere) at above sea level.
