By the late 14th century San Giorgio had grown into a town, and had two main residential zones, above and below the church. These were referred to as "di sopra" (above), and "di bascio" (below). At the same time, San Giorgio grew large enough to absorb the nearby town of "San Aniello a Cambrano", and the centre of the new larger town remained the hilltop church venerated to Saint George. By the 15th century, this church had once again been renovated, this time in high Gothic architecture, and incorporated three new naves. Despite the improvements to the hilltop church, in 1570 the religious centre of San Giorgio was moved further downhill with the opening of the newly built church of "Santa Maria del Principio", around which a prosperous new town centre soon grew. Following the opening of the new church, the procession route was altered to begin at Santa Maria del Principio and run a more regular course through the streets to the hills and back down to the lower end of the commune, giving greater access to the residents to the processional route.
