St Peter’s Square feels less like a piazza than a vast open nave. Bernini’s plan draws you in two steps: a trapezoid that pulls you towards the basilica, then a great oval where double colonnades curve like embracing arms. At the centre the ancient Egyptian obelisk, paired with two fountains, fixes a calm three-point geometry. The space is theatrical and tightly controlled, built to contain processions, papal blessings and today’s televised gatherings. Above, a ring of stone saints lines the entablature, so that anyone standing in the square is held inside a frame of architecture, history and the global gaze of contemporary Catholicism.
