Piazza Vittorio is Rome's biggest square, arcaded on all four sides, and the quarter around it is where the city is most mixed. The shops under the arcades and along the side streets are Chinese, Bangladeshi, Indian, Egyptian and Nigerian as well as Italian, and the covered market two streets away sells the vegetables and spices those kitchens need. In the garden at the centre of the square stand the brick arches of a Roman fountain that once ended an aqueduct.
Beside them is a doorway cut all over with alchemical formulae, moved here when the villa it belonged to was pulled down, and it is the only alchemist's door left standing anywhere. The square itself was built for a city that had just become a capital. When Italy took Rome in 1870 the population doubled within a generation, and this quarter went up at speed on the grounds of villas that were sold off and demolished. The arcades were copied from Turin, so that the new capital would look like a northern one. This is a working quarter rather than a pretty one, and the main station is on one side.
