Archaeological Site of St Peter's Cathedral

The remains of churches pre-dating the Cathedral are hidden beneath this ancient building, the oldest dating back to the 4th century. But the ground underneath St Peter's also holds evidence of the hill’s occupation as far back as the pre-Christian era: wells, wheat processing areas, buildings of potential cultural use and tombs of the Celtic Allobroge tribe. Several spaces have been specially fitted out and are presented with modern museum techniques – one of the most significant archaeological sites north of the Alps.
