Cenchrea was the eastern port of Corinth from where Paul departed his long stay in Corinth Acts 18:18 Cenchrea was a sacred town of Poseidon, and a cleberation to the goddess of fortune Tyche is noted above the harbour. The western port was known as Lechaeum on the Corinthian gulf. Before the construction of the Corinthian canal, small vessels and all the goods laden on ships would be carried across the isthmus to set sail again on the eastern sidee.
Cenchrea was the home town of Phoebe Rom 16:1,2 and it was here that Paul would set sail on his final voyage back to Jerusalem. He would undertake a vow here, shaving his head in the same manner as the Nazarite Num 6.
