It was wrote in Greek, and they say most likely written in Rome. However, the other two cities you mentioned are also possible locations of where it was written.

None of the above, the dialect doesn't match an urban setting (unlike the Jewish patriarch Matthew, or Luke the gentile doctor, both ofvwhom were almost certainly residents of Damascus). Judging by the idiom, probably rural Syria. Tertullian's second century assertation that it was a ghost written job for Simon Peter has been discredited, the dates don't match. It's apparent that the Temple siege was ongoing, but not resolved, when Mark wrote "gar". That puts it between 65 and 70 CE, Peter was martyred earlier than that. Matthew and Luke both had a copy of Mark's manuscript, as well as their own source material and another mss, since lost, of quotes culled from speeches made by the historical Yeshua. That's why all three tell basically the same story, they're known as the "Synoptic" (through the same eye) Gospels. John was written much later, probably in Alexandria, countering the Gnostic faction of Simon Magus. None of them were written on Rome's side of the Mediterranean, the dialect doesn't fit.
