the floor level of the church had been elevated over the centuries. Several traces of the land use in Roman times have been found. Some fragments of Roman pottery were found in a waste pit in the area in front of the east choir. A bronze fibula was found in the main nave. In the church some tombs have also been excavated. One of them had the walls decorated with the Cross of Lorraine, which dated the grave at the Burgundian period, between 1384-1482. Under a side entrance on the east side of the church, today used as baptistery, it was found the tomb of a woman. Her bones have been dated with C14 and resulted to be the oldest human remains of the church. In total, the rests of 180 people have been found in the church.

In the west choir, where at that moment was the main altar, it was discovered a series of blind niches closed with bricks, and the traces of a portal opened in the original wall and later closed with bricks as well. Once opened, the niches revealed the original medieval plaster, and some traces of the original decoration were still visible.

The two-storeys structure of the choir was a distinctive feature of the Ottonian church, later modified to update the church at the Gothic style and open a high
