CLN is my favourite square in Turin, it is a little square behind Piazza San Carlo (very central) with two fountains with a statue, each representing the Po and Dora rivers (the main rivers of the city).
CLN square was built by Umberto Baglioni in 1937. During the German occupation in World War II the square was notorious for hosting the Gestapo headquarters, located at the Hotel National.
In 1937 the square was known as the square of the two fountains, after the liberation in 1945 the square was renamed Piazza CLN. CLN refers to the National Liberation Committee, formed in Italy at the end of fascism.
This square represents an important piece of history not to be forgotten. Piazza CLN was also the protagonist of a major movie by Dario Silver: Profondo Rosso.
I suggest you cross the square by night when the lights in the water turn on and the people go to sleep.
