The document summarizes the palaces of power in Rome throughout history. In ancient Rome, the Forum served as the political center. In the Middle Ages, the Lateran Palace, Quirinal Palace, and Castel Sant'Angelo held temporal power. On Vatican Hill, the Apostolic Palace became the pope's residence and St. Peter's Basilica the center of the Catholic Church. In modern times, palaces like the Quirinale and Palazzo Madama became seats of political power in the new Italian nation.
