Why was it so shocking when pope Julius ii wanted to demolish st peter's basilica?

Pope Julius II's desire to demolish St. Peter's Basilica was shocking because the structure was already a significant symbol of Christian faith and a masterpiece of Renaissance architecture. The original basilica, built in the 4th century, held immense historical and spiritual importance for the Catholic Church. His plan to replace it with a grander design, spearheaded by architects like Bramante, was controversial, as it challenged the established reverence for the existing site. This bold move signified a transformative shift in church architecture and the expression of papal power during the Renaissance.
