Church of San Paolo a Ripa d'Arno for the little ones
This church, although it never was, is called 'the old Cathedral', perhaps due to its importance, or perhaps because important city functions were celebrated there. The façade hides many relief details: Can you see the snake? (Answer 2 at the bottom of the page).
In front of the façade there is a square with benches, crowned with lime trees, a good place to play and run. On the right side a small playground for you.

On the second floor of the walkable loggias, second column from the left.
