Ok for the tree and thanks for the info about apps.
I am trying as well to inform the municipality to promote this artistic initiative on their website (since I know how to reach them :-)). In fact, Giubiasco was a municipality before, but became a neighborhood of Bellinzona some years ago, so... Apparently the "Arte per Arte" artistic exhibition is as well spread in other municipalities around (I am quite sure about Monte Carasso, I do not know the others), it would be good if I could have more info in order to map the other sculptures too.
