Porta Magna - San Petronio

Porta Magna is a Gothic portal at the entrance of San Petronio Basilica featuring ten relief panels on the doorposts that depict scenes from Genesis. The opening is framed by an arched vault decorated with carved details and topped by a central sculptural composition.

Construction of the portal began in 1425 under papal legate Louis Aleman and finished in 1434, with sculptor Jacopo della Quercia directing the artistic work. This creation occurred during a period of significant artistic activity in Bologna and marked a turning point in northern Italian architecture.

The main entrance displays eighteen prophets carved into the side sections, while the curved area above features a statue of Madonna with Child flanked by Saints Ambrose and Petronius. These images served as visual storytelling for visitors who could not read, making biblical narratives accessible to everyone entering the church.

The portal sits at the basilica entrance facing Piazza Maggiore and is easily visible and accessible from the square. Visitors get the best view of the carved details by standing directly in front of the doorway, where light hits the relief panels.

The young Michelangelo Buonarroti studied the sculptural techniques of Jacopo della Quercia at this portal and drew inspiration from the style for his own works. This artistic connection makes the location a key point in the development of Renaissance sculpture.
