"A Latin cross or crux immissa is a type of cross in which the vertical beam sticks above the crossbeam, with the three upper arms either equally long or with the vertical topmost arm shorter than the two horizontal arms, and always with a much longer bottom arm.
If displayed upside down it is called St. Peter´s Cross, because he was reputedly executed on this type of cross. When displayed sideways it is called St. Philip´s cross for the same reason." - (en.wikipedia.org 26.02.2022)
