The flag of Vatican City was adopted on June 7, 1929, the year Pope Pius XI signed the Lateran Treaty with Italy, creating a new independent state governed by the Holy See. The Vatican flag is modeled on the flag of the earlier Papal States.
The flag consists of two vertical bands, one of gold (hoist side) and one of white with the crossed keys of Saint Peter and the Papal Tiara centered in the white band. The crossed keys consist of a golden and a silver key, in which the silver key is placed in the dexter position. The flag is one of only two square country flags in the world, the other being the flag of Switzerland. The yellow and white stripes break the heraldic rule of tincture.
The Papal Basilica of Saint Peter (Latin: Basilica Sancti Petri), officially known in Italian as Basilica Papale di San Pietro in Vaticano and commonly known as Saint Peter's Basilica, is a Late Renaissance church located within the Vatican City.
