The grid of streets immediately south of Porta Nuova station was an immigrant working-class quarter for most of the twentieth century — first from southern Italy, then from North Africa and West Africa. In the 2000s the students arrived; today it is the most diverse neighbourhood in Turin and the most interesting place to eat.
San Salvario contains the city's main synagogue (a Moorish-style 1884 building), a half-dozen mosques, several Eritrean restaurants, the historic Loris market on Via Madama Cristina, and a particularly dense cluster of cocktail bars on Via Berthollet. Walk from Piazza Madama Cristina south to the Parco del Valentino on any evening to see Turin at its most cosmopolitan.
