San Ponzo Semola (hamlet of Ponte Nizza) is a village in the Oltrepò Pavese located on the left bank of the Staffora stream along the Voghera – Varzi “greenway” cycle/pedestrian path. The medieval portion of the town with its characteristic stone houses is located south of the town center at the foot of the small wooded valley of the Semola stream. San Ponzo was one of the railway stations on the Voghera-Varzi line, active between 1931 and 1966.
In this timeless village stands the ancient church of San Ponzo, modified in 1400 without its medieval architectural features having been completely lost. Inside there are traces of frescoes and a stone baptismal font from 1161.
Of note, the area of the Caves of San Ponzo and the Giaciglio del Santo can be reached with a short excursion on foot along the path that goes up to Guardamonte. Legend has it that in these caves in the third century AD. lived the holy hermit and martyr.
Near the caves, the centuries-old "Grande Vecchio" tree of San Ponzo can be admired, although little reported.
