Your Secret place in Florence is...

Piazzale Michelangelo

The Piazzale Michelangelo was built on the hill south of the historic center of Florence following the design of the architect Giuseppe Poggi. Florence was the capital of Italy in this period, 1869, and the entire city underwent intense urban renewal, the "lungarni" (the streets that follow the course of the Arno) were created; on the right side, in the place of the 14th century walls, the Circunvalación was opened and on the left side an 8 km tree-lined panoramic street was traced, currently called Viale dei Colli, on top of which Piazzale Michelangelo was built, as a panoramic terrace over the city.
