Galleria Subalpina
A covered arcade of 1874 in iron, glass and stucco, between piazza Castello and piazza Carlo Alberto: free to walk through and thirty seconds long, which is why almost everyone misses it while passing right by. Inside are a historic café, an antiquarian bookshop and an arthouse cinema. It is the right place when it rains and you are in the centre without a plan; the best light for photographs is mid-morning, when it comes through the roof.
