Where was Saint Andrew crucified?

Historically we know nothing about Saint Andrew, where he travelled and where or how he died. However various Christian traditions, mainly from the third century and later, have him travelling to Achaia Bithynia, Byzantium, Cappadocia, Galatia, Georgia, Macedonia, Romania, Scythia, Ukraine. In other Words, anywhere that pious Christians might have wanted to be associated with a true disciple from the distant past. Even the legend of his crucifixion on an X-shaped cross is very much in doubt, being too suspiciously similar to the legend of Peter's crucifixion to be plausible. The most popular tradition is that Andrew was martyred by crucifixion at the city of Patras (Patræ) in Achaea, on the northern coast of the Peloponnese.
