About 4 blocks down the Via Domenico Scarlatti from the Corso Buenos Aires, there is a block of public gardens. If the gardens have a name, Google Maps doesn't know it and I don't recall seeing any signs showing what it is. (Normally if I see a sign at a location, I will take a reference shot of it.)

Within the garden, we can see marked out a course for the children's game of Campana; or, in English, hopscotch. The pattern is a little bit different to the usual layout where (in both English and Italian) you normally have 3 single spaces, then two, then one, then 2, then a place to turn around and go back. In this case we have 2 double spaces together so it may well be aimed at younger children.

I have no idea what that circular area in the centre is for. At least the park provides an oasis of greenery for the surrounding apartment buildings to look out on.
