Tocco Caudio is a village and comune in the province of Benevento, in the Campania region of southern Italy.

As with many ancient Longobard towns in this mountainous region of southern Italy, Tocco Caudio was built on a promontory ridge.

This arrangement made the town easily defensible, while having ready access to ridge-top roads along which a traveller would not need to cross any rivers.

Also, as was typical with medieval development, the town is fairly compact with narrow streets.

Rather than attempt to rebuild the historic town, the citizens opted to completely abandon it and resettle around the ridge.
