Piazza Castello / ตูริน

This is THE main square in Turin.
When you walk around it, you seem to change historical periods: on one side there is an original medioeval castle, on the other one the luxury royal palaces of the previous monarchs.
In addition, the whole piazza is surrounded by arcades and shops underneath, so this is beautiful to visit even in a cloudy or rainy day.

The museums of Polo Reale and Palazzo Madama are right here.
