At St. Peter's Square, Gian Lorenzo Bernini's colonnades curve outward in what he described as "the maternal arms of the Church."
Inside St. Peter's Basilica — built over the tomb of the Apostle Peter and completed in 1626 — Renaissance and Baroque genius converge. Michelangelo's dome rises above marble and light, completing a building that took over a century to realize and draws on the work of Bramante, Raphael, and Maderno alongside Michelangelo himself. To stand beneath it is to understand what it meant to commission a building not for a lifetime, but for centuries.
