I did the following: 
- Removed all 'senza titolo' names in https://www.openstreetmap.org/changeset/154985922
- Changed https://www.openstreetmap.org/changeset/154986871 from being both a tree and an artwork
- Updated the wikimedia_commons links in https://www.openstreetmap.org/changeset/154986981 so that they do not have URL-encoded values in them

Happy mapping,
