Tarsus is the correct answer.

Paul stood on the steps and motioned to the crowd.  When they were all silent, he said to them in Aramaic:

"Brothers and fathers, listen now to my defense."

When they heard him speak to them in Aramaic, they became very quiet.  Then Paul said:

"I am a Jew, born in Tarsus, of Cilicia, but brought up in this city.  Under Gamaliel I was thoroughly trained in the law of our fathers and was just as zealous for God as any of you are today.

Acts 21:40, 22:1-3
