Step inside one of the ancient world's greatest wonders, a temple built nearly 2,000 years ago and still standing strong. Beneath the towering columns, you'll enter a space that has left visitors speechless for twenty centuries. Look up at the mighty dome, still the largest of its kind on Earth and the oculus at its center, open to the open sky. Watch sunlight pour through and drift slowly across the marble, just as it has for generations. Wander past the niches where Roman gods once stood, and pause at the tomb of Raphael, who chose to rest here forever. Take a quiet moment beneath the oculus, where earth and sky seem to meet and let yourself feel the wonder of a place that has outlived empires.
