Via Caecilia, an ancient highroad of Italy, which diverged from the Via Salaria at the 35th m. from Rome, and ran by Amiternum to the Adriatic coast, passing probably by Hadria. A branch ran to Interamna Praetuttiorum (Teramo) and thence probably to the sea at Castrum Novum (Giulianova), a distance of about 151 m. from Rome. It was probably constructed by L. Caecilius Metellus Diadematus (consul in 117 B.C.).
