Initially limited to the confluence basin, the town gradually grew to reach the plateaus, the neighbouring valleys and finally to the railway station which was built in 1886.
The lower city was initially the city of the commoners; full of craftsmen, commerce and rural life (there were 6 farms within the city walls), then
from the middle of the sixteenth century, it became home to the “river companions“.
From the eighteenth century, the new merchant bourgeoisie, particularly linked to the timber trade, settled there.
Finally, the lower town definitively became the centre of political power in the nineteenth century, when the majestic building housing the Town Hall was built in 1842.
