If 2 or 3, yes. If 1,000s - no. Currently lots of wikipedia and wikidata values are just linked to much higher level concepts (e.g. here), which isn’t really helpful.
Even though the wikipedia article conflates different subjects, wikidata elements should be created for all the different concepts, frankly Wikipedia should too.
The urban park
The National Historic Site
The neighbourghood (boundary + locality node)
EDIT: The elements in OSM were wrongly mapped, I updated them according to official documentation Changeset: 177304674 | OpenStreetMap That should alleviate some confusion
That’s a sprawling article. The multiple infoboxes are a red flag that it should be split apart. Similarly, the Wikidata item’s multiple conflicting inception (P571) statements trigger a validator warning, so clearly the item should be split apart. If Wikipedians prefer to keep it all together in one place for notability reasons, then the Wikidata item should be an instance of Wikimedia article covering multiple topics (Q21484471), linking to separate items about each of the more specific topics. Then there would be no conflict on the OSM side.
