Thomas Ashby, 1911 Encyclopædia Britannica, Volume 4… (1911)
“ The coast of the Gulf not only between Caietae Portus and Formiae, but E. of the latter also, as far as the modern Monte Scauri, was a favourite summer resort (see Formia) . Cicero may have had villas both at Portus Caietae and at Formiae [1] proper, and the emperors certainly possessed property at both places. After the destruction of Formiae in A.D. 847 it became one of the most important seaports of central Italy (see Gaeta) . In the town are scanty remains of an amphitheatre and theatre: near the church of La Trinità, higher up, are remains of a large reservoir. ”
