On 18 November 1626, St Peter's Basilica in Rome was consecrated, marking the completion of an architectural and artistic masterpiece that would become the world's largest Christian church.
Built over a span of more than a century, the new basilica replaced an earlier structure dating back to the 4th century, commissioned by Emperor Constantine.
The magnificent edifice, designed by a succession of renowned architects including Bramante, Michelangelo, and Bernini, stands as a testament to the grandeur of Renaissance and Baroque art and architecture.
Its towering dome, awe-inspiring interiors, and intricate sculptures continue to inspire millions of pilgrims and visitors, symbolising the power and spiritual significance of the Roman Catholic Church.
