Vatican City Flag - Official National Flag and Symbol #303081 (License: Personal Use)

The flag consists of two equal vertical bands: golden yellow on the hoist side and white on the fly side. Centered on the white band is the coat of arms of the Holy See, featuring the crossed keys of Saint Peter (one gold, one silver) tied with a red cord and topped by a papal tiara. This design reflects the dual spiritual and temporal authority of the Pope as head of the Catholic Church and sovereign of Vatican City State.
