This "Maasikad Viljandis" is rather merely a descrption used in particular source, not a name of individual sculptures. See https://wiki.openstreetmap.org/wiki/Names#Name_is_the_name_only. This is also why I corrected previous name="Kondas-Strawberry" for individual sculptures to description="Betoonist maasikas" (see https://pewu.github.io/osm-history/#/node/2147829408).

Also, I believe this relation is redundant as per https://wiki.openstreetmap.org/wiki/Relations_are_not_categories. Its transportation related site=stop_area in particular makes little sense.
