The diocese was established, perhaps around 400 AD, in Paestum, the Ancient Greco-Roman city now called Pesto in Italian.
[1] Louis Duchesne remarks that, in Lucania, after the Gothic War (535–554), there were seven bishoprics; after the Lombards arrived, six of them were destroyed; the only one that survived was Paestum, which was compelled to abandon its seat and seek refuge in the Byzantine fort of Arropolis.
Circumstances surrounding the date of 750 are unattested, and the exact location of Consilina is uncertain.
[5] In the 11th century, the bishops of Paestum moved their headquarters, without yet changing their title, to the city of Capaccio.
[6] The title, though not the diocese, was nominally restored as a Latin Catholic titular bishopric in 1966.
