Well preserved is the Arch of Porta Nuova, architecturally joined to the adjacent Clock Tower from which it takes its name and whose fornice is embellished with interesting reimplements of Roman times.
In front of the arch are placed, in fact, two limestone lions (end of I sec. a.c. - beginning of I sec. d.c.), while inside the fornix there is a relief with the frontal representation of two deceased spouses (end of I sec. a.c.) and three epigraphs, including one with the names of the duoviri C. Statius and Q. Castrius, attesting that Ascoli was municipium to duoviral constitution.
The Clock Tower rises on the left of the arch and is part of the Palazzo della Pretura. It is an elegant tower in neoclassical style that encloses between twin columns a clock; at its top an iron structure supports two small bells.
