What is the name of this saint?

I visited Italy a couple of years ago and while I was in Bari, I visited a church with the body of a saint in it. It was an incorruptable one. Her body was fully intact and inside a Gl case where you could fully see her. I want to say her name is Saint Cecilia but I'm not sure if she was from there or not. I know Saint Nicolas' bones are in Bari too. I saw them. But he wasn't originally from there he was moved there. So could you help me?
