Vexillological description
It is a rectangular field with a 2:3 ratio divided diagonally, with the keys of St Peter in the centre.
- Divisions
- two triangles: one gold by the flagpole and another white on the free side, separated by the diagonal that runs from the upper corner of the flagpole to the lower one of the fly side.
- Emblem
- two crossed keys —one gold and one silver —with the bits (the ends) pointing downwards, tied with a red and blue cord, and above them the three-crowned papal tiara.
- Variant
- on the processional flag the division is vertical, with the gold at the flagpole.
