A few kilometers from Montorio al Vomano, in loc. Venaquila, going along a short trail leading to river Vomano, you will reach Hercules Temple. Of great historical-archaeological importance, this Roman temple was discovered in 1865. Of the structure, significant rests of the cell with a mosaic floor remain: the floor was made in opus tessellatum with white limestone tesserae and black tesserae for the outlines. On the floor, the dedication inscription that, thanks to the mention of the consul couple, can be dated back to the 55 BC.
