The Vatican Palaces are a series of buildings and architectural complexes located within the Vatican City, in Rome. These palaces have been the official residence of the Popes since the transfer of the pontifical seat to the Vatican in the 14th century. Initially, the palace was simple and located near the Lateran Basilica, but over the centuries it was expanded and embellished by different popes and architects. During the Renaissance in the 15th century, the Vatican Palaces became an important center of art and architecture. Pope Nicholas V promoted their transformation and oversaw the construction of the chapel with frescoes by Fra Angelico. Subsequently, the Apostolic Library and the Sistine Chapel were built, becoming important artistic spaces within the Vatican Palaces. Various popes, such as Alexander VI, Julius II, and Leo X, continued to embellish the palaces with artistic commissions and architectural restructurings. The Belvedere Courtyard, the Pinecone Courtyard, and the Saint Damasus Courtyard were built during that time. In summary, the Vatican Palaces are a collection of historic buildings that have served as the residence and art center of the Popes throughout the centuries, with important works of art and Renaissance architecture.
