And now the walk takes us outside the city walls. We go down Via Mazzini, pass through the gate of San Nicola, now called the gate of san Francesco, with its cylindrical tower still visible, so that we can get to the rain gulley (La Lama) by walking down Via Rossini and Via Mercadante outside the city walls.This fascinating corner is worth stopping to look at because it is a small natural amphitheatre created between the simple dwellings placed between stairways and galleries: a unique architectural example of creative popular resourcefulness.
