In the ancient religious complex of San Felice, in the 17th-century Capuchin convent, transformed into a prison after the unification of Italy, the Archaeological Superintendency has now its seat.

In the latter, various Roman tombstones are exhibited to the public, but most importantly the original fossil of the Scipionyx samniticus, known as "Ciro", found in Pietraroja, where a copy is present at the Paleolab, the museum of geology and paleontology that re-proposes the territory where that dinosaur species lived over 110 million years ago.
