The Vatican's square is in front of St. Peter's Cathedral. It is Rome's largest square, Baroque style, can accommodate 500,000 people, is the Holy See used to engage in large-scale religious activities. Located on the West Bank of the Taipo River. There is a limestone border in front of the square. It is named after St. Peter's Church on the front of the square. Because the Vatican's borders are all bordered by walls except St. Peter's Square, Italy does not recognize St. Peter's Square as belonging to the Vatican. The square is slightly oval and the ground is paved with small black squares. Two sets of semi-circular marble corridors surround the two sides, forming three grand corridors. These two groups of corridors are decorative buildings of the Vatican. They are composed of 284 circular dwellings and 88 square columns, forming three corridors. These pillars are arranged on both sides of the square like a queue of four people. The pillar is 18 meters high and needs three or four people to embrace. On the top of each pillar on the side of the Plaza, there is a marble statue. They are all saints and saints in the history of the Roman Catholic Church. They have different and vivid manners. In the center of the square stands an obelisk, and between the bronze lions there are eagles, flying like wings. The stone tablet, originally decorated by the Roman Emperor Caligula as a circular square beside the palace, was transported from Egypt. In 1586, Pope Sistine V ordered the stone tablet to be moved to St. Peter's Square. It is said that more than 900 workers, 150 horses and 47 lifting devices were mobilized for this purpose. It took nearly five months to complete the relocation project. There are two well-shaped fountains on both sides of the square, which are also legendary works of famous artists. Spring water sprays upward from the middle and divides into two layers. The upper layer is mushroom-shaped, and the water column falls down to form a water curtain around it. The lower layer is bowl-shaped, which receives the spring water as a fine overflow and murmurs. The square and its adjacent colonnades were designed by renowned architect and sculptor Bernini in 1656 and completed in 11 years. The marble statues on the top of the pillars were carved by Bernini and his students. Bernini is famous for his Baroque art which advocates magnificence and exaggeration.
