Monte Spineto, Mountain summit in Province of Alessandria, Italy

Monte Spineto is a 459-metre summit at the end of the Ligurian Apennines, on the divide between the Scrivia and Borbera valleys, entirely within the municipality of Stazzano. Its top holds the Santuario di Nostra Signora del Monte Spineto, begun in 1633 under Bishop Paolo Arese of Tortona, and a RAI transmitter.

In the early Middle Ages the mountain was called Monte Arimanno, and in the late Middle Ages Monte Spigno. In 1633 construction of the Sanctuary of Nostra Signora del Monte Spineto began on the summit, commissioned by Paolo Arese, bishop of Tortona. A major landslide on 2 January 2017 at 7:18 sent thousands of cubic metres of rock down the slopes.
