 St. Peter's Basilica is meant to stand as a sign of the Church's unity on earth. In the Protestant Reformation, one of the greatest divisions in Christian history occurred in the extensive effort to complete the building project of this very basilica. On November 18th, 1626, the new St. Peter's Basilica was consecrated by Pope Urban VIII, St. Peter's 234th successor. The greatest of the Renaissance and Baroque artists were involved, Raphael, Michelangelo, Fontana, Della Porta, and Moderna. From Bremante to Bernini, the basilica took 120 years, seven chief architects, and 20 popes to come to the point of dedication as a fitting sanctuary for the bones of St. Peter.
