Cassandreia

It was located on the site of the earlier Ancient Greek city of Potidaea, at the isthmus of the Pallene peninsula.

[2] At the end of the Roman Republic, around 43 BC by order of Brutus a Roman colony was settled by the proconsul Q. Hortensius Hortalus, which in 30 BC was resettled by August with the installation of new settlers and took the official name Colonia Iulia Augusta Cassandrensis.

[3] The territory of the colony had included within its boundaries the peninsula of Pallini and the district stretched north of the canal to the foot of the mountain Cholomontas.

The Christian diocese based on the ancient town is mentioned in the early 10th-century Notitiae Episcopatuum of Byzantine Emperor Leo VI the Wise.

[6][7] In addition to the ancient Greek Orthodox metropolis (el), Cassandria is also listed today by the Catholic Church as a titular see.
