I think its in Antioch
The three places of Pauls journey were Corinth, Antioch and Thesolonica.
Missionary
Paul's missionary journeys took place primarily in the first century AD, with his first journey starting around 46-47 AD and his last journey occurring around 54-57 AD. These journeys are documented in the New Testament, particularly in the Book of Acts. Paul's travels aimed to spread Christianity throughout the Roman Empire, including regions such as Asia Minor and Greece.
Paul's First Missionary Journey. Recorded in Acts 13: 1 to 13
Pauls first mission occurred in A.D. 47. The Book of Acts records this in Acts 13:2-14:28. The earliest of Paul's Epistles, Galations (A.D. 48), 1 and 2 Thess. (A.D. 50), occurred during Paul's second journey.
Silas (Acts 15:40) Timothy was added at Lystra Acts 16:1-3. Luke is the recognized author of Acts and has references later in chapter 16 that use the pronoun "we" so he was apparently with them on this trip.
Many biblical scholars believe that the first missionary journey of Paul of Tarsus was to Cyprus. There is not 100% agreement with this however.

Barnabas was Paul's companion on his first missionary journey. They traveled together to Cyprus and Asia Minor to preach the gospel and establish churches.
2 years
The first place Paul and Barnabas visited on their missionary journey was Cyprus. After being sent out by the church in Antioch, they arrived at Salamis, a city on the eastern side of the island, where they proclaimed the word of God in the synagogues. Their journey in Cyprus marked the beginning of their missionary activities, which aimed to spread Christianity to various regions.
1st Missionary Journey - Barnabas. 2nd Missionary Journey - Silas. 3rd Missionary Journey - mostly alone, but assisted at various times by Luke, Timothy or Titus.
